Using opk as a pregnancy test? ?

Question

Been told that you can use a opk as a pregnancy test.. If the opk is positive right before af you're Pregnant?
I don't believe it, but am tempted to do it as I've run out of pregnancy tests.
Anyone heard of this?

Answer

This is definitely true because my girlfriend just used about 5 wondfo OPK to confirm pregnancy and they were as positive as they get, then took a digital hpt and it said she is 2-3 weeks pregnant. She was 2 days late on her AF when she tested.

Answer

I tested it when I first got my BFP and my OPKs were positive, too!
