Help with OPK test

Today I used my first ovulation test just trying to watch my cycle a little more closely. I assume I will ovulate this coming Wednesday as the first day of last AF was 18th May, and normally I am bang on 28days. So today i tested and a faint second line came up. The packet says this means you will ovulate in the next 24-36hrs. So if I test again tomorrow and the next day will the lines get darker as it gets closer to O and on O day??
Or do I just assume it will be the next few days considering the second line??

Thanks in Advance!

If the line is feint it's usually negative. With OPK's it's only positive if the test line is as dark or darker than the control line. For me, I didn't find they got progressively darker as I got closer to O. I also found that charting my temperature helped pinpoint ovulation because until I got used to them I found OPK's quite hard to interpret sometimes. For a 28 day cycle I would start testing around day 10 just in case you O earlier than the normal day 14.. GL :)

Thanks for the reply. I thought it was going to be a simple as POAS!

hmmm so do you think day 12 (today) is too late to start?? Temp is probably a good idea too. Although we are not TTC I am wondering what happens in my cycle because the O symptoms change each month.
I appreciate your answer, I still can't believe it's not just a case of reading the lines! lol

No day 12 should be fine.. Also best at the same time of the day. 2pm is apparently the best time, but I did mine between 12 and 1.. Not as simple as POAS unfortunately lol.. They are exxy too. You can get cheap ones on E bay, I did and they work.. I found temping and OPK's good.. Either one by themselves I found too confusing. I liked to see a pattern of positive OPK's and temp dips lol..

does anyone know if the ebay opks are as sensitive as the first response ones at woolies?

first month i got a + on FR and ovulated

this month still waiting for o and getting faint lines on ebay ones. should i try FR again?

charting as well and temps not indicating o - just wondering.

I used cheap (very cheap, $20 for 50 tests or something) OPK's and it worked for me! If temps aren't indicating O, and lines are only feint, I would say maybe you aren't ovulating. Have you had a progesterone blood test 7DPO? If not, I'd be off to the Dr's..

I just looked at your chart and maybe you ovulate late?

thanks.

yeah my cycles are supercrazy from coming off the pill. getting ultrasound on wednesday.

was just wondering if there was any point in buying some FR from woolies to see if the result it different to the ebay ones.

havent had any blood tests since coming off the pill. think its prob a good idea.

when is the best time in my cycle to have a blood test? 7DPO?

I found the e bay ones worked for me, but if you feel the FR are more reliable then use them.. I would maybe wait this cycle out and if your chart shows you O'd but there was no +opk, then maybe try a different brand.. The Dr normally does a progesterone test day 21 of your cycle, but that's assuming you ovulate on day 14, which some people don't.. Good Luck. Hope your TTC journey is short.

thank good advice. i'll see how i go. i'll see what happens with the u/s, and perhaps get a blood test if needed. fx for o.

Hey Mich,

OPKs might not work for you if you've been diagnosed with PCO. I tried to use them for my last cycle and had a couple of false positives... I had a positive AFTER I actually O'd too... weird I know. I'm going to keep using them, but I probably won't rely on them IYKWIM.
