What was your first Beta HCG result?

Just curious.

To all those who have had a successful cycle, what was your first beta HCG result (number-wise)??

How many days past transfer/ovulation was it?

Just interested :) thanks!

Not sure if you're interested in natural pregnancies, but mine were 42 (about 4 weeks) - this ended in a miscarriage and 179 (around 3w 5d) - resulted in DD

With Charlie I was something like just over 70 at 13dpo, 8dpt.

N2L it was 2069 at 19 days post-fertilization (14 days post transfer of 5 day blastie). I just went back in time in the forum to find where I posted that :)

Mine was 396 at 16 days past the trigger shot, so I'm guessing 14dpo.

213 15dpo (13dpt 2x d2)

Mine was 103 at 10dp3dt and then 711 at 14dp3dt!!!

120 at 10dpt of one day 5 blasti.

27 at 16 days post IUI

With DD1 at 16dpo (14dpt) it was 480 at 19dpo it was 2,038.

With DD2 (current pregnacy) it was 233 at 15dpo (13dpt).

300 at 11dp3dt of two little embies that are now nicely baking away :)

1- 196 16dpo
2- 20 ( chem preg)
3-140 16 or 17dpo
4-334 15dpo

why are we asking??

1st preg 5-6 weeks 26000 something- was blighted ovum
2nd preg 5-6 weeks 2629 - so far all good, Dr said thyroid levels still a bit up so could be why 1st so high and this 'normalish'

Thanks everyone :)

The reason I was asking was to determine the day that you can reasonably determine an IVF cycle hasn't been successful through hpt testing.

For instance, if, say the average HCG at 14dpo (whether that be 9dp5dt or 11dp3dt) is 100, then going by the theory HCG doubles every 48 hours or so, then if you get a bfn on a 10mui hpt on 10 or 11 dpo or later, then there's a very, very good chance that the cycle has not been successful.

Hey lovely

I did got my first lot of two line at equivalent 12dpo (9dp3dt) and the second line was VERY faint using super dooper sensitive tests. I honestly don't think that I would've got that second line had I tested the day before.
I so want that second line to come up for you this time round

Thanks Melissa :)

Do you remember the sensitivity (or brand) of your hpts?

(recognize and remember the desperation? :lol: )

Sorry hun, I had a stash of them but can't remember. Would need to go and peruse the different boxes to jog my memory. I THINK it could have been an early first response one (I know the pg tests we use at work measure down to 25 which wasn't sensitive enough for my liking so I am guessing this reads lower?). It is a bit weird though because at that stage, I would guess my hcg would've been about 100 - 150 but the line was still extremely faint, like twisting test from side to side faint so it does make me wonder how much bearing the sensitivity has on the actual hcg reading iykwim

Yup, remember that feeling of despair all too well and you would think by now, I could actually start believing that it is true. God our minds can play crap tricks on us :rolleyes:

I'd say by 12dpo, using a sensitive HPT, most pregnant women will get a BFP.

There are always exceptions to the rule though. In particular, if you start talking about FETs, I've seen some very low, slow-rising hcg levels result in a healthy child, which might mean those mums didn't get a BFP until after 14dpo. That doesn't happen so much with fresh IVF, IUI or natural pregnancies though.

Another thing to consider is that, while 100 is the average for 14dpo, some are higher and some are lower. The number might only be 40 at 14dpo (but then go on to double niclely). When would you expect a +HPT then? Have you checked out betabase for the range of beta values by DPO?

With DS1, I got a BFP at 8dpo but didn't get a blood test until I was 21dpo, when HCG was 6209.

For DS2, I only got a BFP at 13dpo (and I was POAS from 5dpo). HCG was 51 at 14dpo and 834 at 20dpo.

I was testing with FRERs. These were natural cycles

Hey, my results were all natural cycles (using OPKs) so I'm not sure if this helps. If you want to do some maths on the numbers though - here goes:

M/C 1: HCG 73 at 11 dpo (BFP on FRER at 8 dpo)

M/C 2: HCG 98 at 15 dpo (BFP on FRER at 9 dpo)

Current preg: HCG 21 at 10 dpo, 306 at 14 dpo, 8656 at 21 dpo (BFP on FRER at 9 dpo)

N2L I had a super feint BFP at 9dpo on FRER. But remember levels are different every time. I think I always faced facts a cycle was over if no line by 12dpo. Just checking you know of the website betabase.info? I think this is the best indicator of hcg levels at dp and you can segment by age if this might help. Fingers crossed it is still to come for you this cycle xxx

N2L I got my first BFP on a FRER at 9dp3dt, it was light but I didnt need to squint or anything, it was def there.

Best of luck xxx

Problem is that pregnancy tests detect regular hcg where as H-hcg is what we produce initally and this is not detected on hpt. However H-hcg is detected with blood tests.

Does that make sense?

ETA: I recall reading a study on hpts a few months ago and if I remember correctly some of the most sensitive tests are really bad at detecting H-hcg, but there are a couple of tests that have lower sensitivity that are much better at detecting H-hcg so can detect pregnancy earlier then the more "sensitive" tests.

I'm going to add mine so that anyone reading this later on can have them.

HCG 441 - at 14dp3dt Fresh = DD2
HCG 530 - at 14dp5dt FET = Blighted Ovum
HCG 701 - at 12dp5dt Fresh = Heartbeat so far

With the last results I got my first + HPT on a FRER at 5dp5dt. It was light but not so light you had to hold it just right with you toungue out standing on your head.
I got my first +HPT on a Lullaby Conceptions HPT at 4dp5dt. It wasn't a squinty one either although it was light.

Hi Ladies

Just thought I would chime in with DS at D35 post 1 x fresh 5 day transfer my HCG wass 476, I found out today im pregnant D35 post 1x frozen embryo transfer. Does this mean its twins?? Oh and I have very low progesterone despite 2500mg a day? Any thoughts gratefully received.

Bee

Bee - The only way to know if it's twins is to have a scan. Levels "could" indicate more than 1 but it can also just indicate 1 really strong singleton. Whatever you do don't google your levels. It will only drive you bonkers and it did me.

All my FB IVF mums and to some extent my clinic were indicating to me it was twins and so I had got my hopes right up expecting twins on my scan. I was really disapointed it wasn't. I'm angry at myself for even entertaining the idea of twins. So I learned my lesson on not to analize you levels too closely. Scans are more accurate.

Hope that helps. I don't want to burst your bubble. I just don't want you to go through what I have just been through.

Big congratulations on your BFP!

My first HCG with DS2 was at 20dpo (according to my FS, but according to my OPK was 17Dpo so not sure) was 1347., and progesterone was over 100, where as with DS1 HCG at 16 dpo was around 400, but progesterone was below 60, so diff results each time. Agree you shouldnt reflect on the numbers too much!!
