Does positive OPK=BFP?

Question

Ok ladies! I'm trying not to get too excited but I read on peeonastick.com that OPK sticks can be used as HPTs. I bought a month supply of First Response OPK sticks last month and O'ed on July 30th. I took an OPK stick today and got a positive for ovulating...but here's the problem, I had my niece over this weekend and she must have seen the OPK box in my bathroom and opened it because the resealable pouch was open when I got the stick out. I'm wondering if this would effect the test results? Can't find info on the consequences of not closing the pouch immediately? HELP!? Will likely use HPT tomorrow morning but just wanted to look for answers now. Thanks ladies :)

Answer 1

Well, with me i used an opk just to test and got a positive. Then, a couple days later i used and hpt and also got a positive. I wouldn't put your faith all into the opk but i did it b/c i heard the same thing. This was as of recently. I got a bfp on an hpt the 8 of this month. I don't know if it would effect it being open. Although, it does say to not leave it open i would assume fore a reason. But just a guess...lol  Well, best wishes and sticky baby dust..

Answer 2

It is certainly possible. HcG and LH hormone are very similar and OPKs do sometimes work as really early HPT.  In fact, HcG shots (acting as proxy for LH) are also used to trigger ovulation in a medicated cycle.

For my wife, OPKs tested positive at 8dpo, and early HPT tested light positive at 9dpo (BFP at 11dpo).

I doubt the pouch had anything to do with it.  Also, you don't have to wait till morning to do HPT.  It is well after past 10 dpo and you don't need morning urine for HPT.  You can test now.

Good luck.

I have an OPK test instruction sheet right in front of me and it says that it can't be used for a pregnancy test. They detect completely different hormones.

OPK = LH

HPT = hCG
