Question

Do OPK test results change as time lapse?

I took an opk at at about 4 pm today. I got busy and didn't read it until about 20 minutes later. Are opk tests similar to hpt in the fact that after the "reading time period" you could get a false reading? This is the darkest it has been yet and I am on cd 26. Any help with this would be wonderful.

They hit full darkness about 10-15mins then start drying. If it takes a bit longer than the allotted time, its not as big of a deal as it is with hpt's becuz u wont get an evap (there's usually always some sort of line). Which ones are u using? If ur having a hard time getting a positive, make sure ur using the most sensitive ones available (20mIU), if ur using say 25, 30 or more, and u only surge to a 22, u'll never get a positive and possibly miss ur window completely.

I'm using Wondfo. I usually get a faint line 50% of the time. This is the first time it's been darker (still lighter than control) though. I think I'll test later tonight to compare.

Wondfo is good, they measure 25. If u want lower, ebay has some good ones with a pink handle. I've been using those for years and love 'em! Its nice that its darker than u usually get tho. Hopefully its nice n dark for ya tonight. How long are ur cycles? Ur sure u O?

I am definitely irregular. Anywhere from 32 days to 5 months. I came off of bc in April. Got a bfp first cycle but it ended in a mc. I actually have a dr appointment tomorrow due to me not o yet. Just hoping for a miracle right away.

Ugh that is so frustrating! Sorry for ur loss!
Ask about clomid at ur appt. It may help induce O for u, if he says no then u could try Soy.
