Found this info, thought it may be of some use to some of you ... (or perhaps just confuse you all!!) (got it off FF)
Is there such a thing as an implantation dip?
There is a great interest in identifying very early pregnancy signs on charts. Which signs can tell you that you might be pregnant? Which are meaningless? To try to answer this question quantitatively, we have run some statistics on a large sample of charts.
One of the most controversial and puzzling potential signs has always been a luteal phase dip. There has been a lot of speculation about the significance of a temperature dip in the days after ovulation around the time implantation would be expected. We wanted to get to the bottom of the issue and find out once and for all if seeing a dip in the luteal phase, around the time of expected implantation, increased the probability of pregnancy.
Here is what we did:
We ran a full statistical analysis on 116,691 charts recently processed by Fertility Friend, both pregnancy charts and charts that did not result in pregnancy.
To be considered as a dip, charts had to show a significant single dip that lasted a single day, occurring between 5 and 12 days past ovulation.
We used a minimum dip size of 0.3F. We also ran the test using several pattern recognition algorithms to validate the correlation independently of the method of measurement.
Here is what we found:
11% of charts that showed ovulation but did not result in a pregnancy displayed this pattern.
23% of charts that showed ovulation and did result in a pregnancy showed this pattern.
Of the pregnancy charts that showed this pattern, the most likely days for the dip to occur were between 7 and 8 days past ovulation.
The data suggest that this pattern is indeed more likely to result in a pregnancy.
Remember, though, if you have this pattern, it does not necessarily mean that you are pregnant. It is just increasing your probability.
No matter your chart pattern, you can still be pregnant as long as you have well-timed intercourse within your fertile time. In the end, the only way to really know for sure whether or not you are pregnant is still when you can reliably take a pregnancy test.
My word, it is quiet in here tonight. I think all the chatter starts after I go to bed. Oh well, Nana is getting sleepy, so I will cuddle into my nice warm bed and put the TV on. Sleep well girlies, chat tomorrow.

Ok I missed waaaaaay too must posting last night! I went to the seminar and luckily it was fairly entertaining and not a snorefest. Unfortunately though it wasn't exactly what me and my work-buddy thought it was going to be. It was a behaviour/training seminar and we thought that the person running the workshop was going to kind of teach us techniques for training and modifying behaviours. Instead it was pretty much a bunch of little videos of her training animals (seals, giraffes, hippos, dolphins, dogs and more), but didn't really give us any new techniques. It was interesting to hear that she trained 4 male dolphins to ejaculate on command (for dolphin artificial insemination) but I wanted to know how she initially trained that kind of behaviour! Did she just hang around until a dolphin pleasured himself then congratulate him?!
Anyway...
Teen and Chappas - I'm very sorry about your losses, but I am very glad that you have found this thread. It's a wonderful place to heal and the girls are all amazingly supportive and compassionate. :hugs:
Teen - Although you are a bit younger than I am, I too have a huge age gap between myself and my DH. For my it's about 15 1/2 years. Sometimes love disregards age yeah?
I think you are doing the right thing in regards to changing drs. You have to feel comfortable and have trust in the doctor that is going to be helping you bring a child into this world.
I hope your TTC going is nice and quick!
Jen - On your marks. Get set. GO!!! I love your plan!! It would never work with my DH. He's just not the competitive type. I hope I get a BFP this month so I don't have to think up a new strategy for next month.
Joey - OMG I accidentally just wrote your name as "Hoey"! I swear I'm not passing judgement on your personal life choices!!! :ROFL I used to embarrass myself by accidentally writing my DH's name as Booby instead of Bobby. Thank god I usually proof read!!!
In regards to dyeing your hair, I've read things that claim it's safe, and then I've read other things to say it's not safe. The ones that say it's unsafe mention that the chemicals can be absorbed into the skin on your head and then get into your blood stream. It recommends that if you are going to dye you hair that you should restrict it to foils that don't touch your skull etc.
Chappas - I hope all the babydust and stickyvibes in this thread give you the luck you need in your TTC journey and that your get your BFP in no time!!!
To all the new girls I'm really sorry you have to be here, but this place is such a wonderful support!! I hope you all get the BFP's you've been trying for asap!!
Jen: Any luck with the waterbed? I told DH and he almost wet himself giggling. yes, he's a giggler!! Our bed is fantastic! It feels like we're staying in a hotel!!
AFM: Well, had work today and was really busy which was good. Got a message this morn from a friend who had her baby last night (we were due around the same time). I'm ok. Really happy for her, but still a bit down. DH didn't take it so well. It's weird when you're so happy for someone but at the same time upset it isn't you.
I've had lower back pain all day and my tummy is really bloated (dammit- have a hot outfit to wear tomorrow night so may have to alter it a bit to hide the bulge). Are those signs of o? I still have the ewcm, which is good. And Dh is more determined than ever that this is our month!! I'm thinking I may now be in the tww.... but who knows?!
Also, got given a piece of art today that's all of these karma sutra positions carved into the bone from a corset. Inspiration much?
Good morning tutmae! Gotta go out and buy me a waterbed first, but I'll begin collecting the scary fish and keeping them in our fish tank till then! I still like the idea of the bed on wheels! I promise I'll wear a helmet! I would say the back pain and bloating are definitely signs of O! Hope DH is still giving his olympic swimmers their little pep talks! The artwork sounds like something you need to keep right by the new bed--it's an omen!
Krystie--Are you still awake??? I would also love to know what the initial training is for ejaculation on command--maybe she's the "Ejaculation Whisperer"! Can she get it to work on our DH's?? That's the real test as to how great of an instructor she really is! Just ring a bell, and BAM ejaculate on command, it could work, you know! Mentioned the competition to DF last night--it's begun already!
chappas--Welcome to our little thread! Hoping you find strength and comfort to help you through your losses, and on your TTC journey! Sending big and hope to get to know you better!
joey-- Check out your mood smilie! It's just gabbing away... Thanks for the info on implantation dips, it's funny--I must've read that thing every single day last month after my temp drop and FF said "possible implantation dip"! You have to read it everyday otherwise the words might change-- I always wanted an alarm to go off saying "You've just won an implantation dip!" or something really noticeable like that!
Implantation Dip
I still like the idea of the bed on wheels!
