So I've been reading, and apparently OPKs will also show up as positive if you're pregnant since they don't discriminate between hormones (here's a link, there are a few if you google). Obviously this wouldn't be reliable for confirmation but i'm thinking since pregnancy tests, good ones anyway, are pretty expensive whereas OPKs are a dime a dozen, it might be worth using them as an indication of whether or not to take a pregnancy test? I wonder then when people say positive OPK = possibly positive pregnancy test, that would mean an OPK where the results line is darker than the control line right?
I am thinking of using OPKs before pregnancy tests so stretch by budget a bit further

OPKs as pregnancy tests??

You have to be pretty high in HcG to register a really dark second line on an OPK. With one of my pgs I didn't know I was pg, used an OPK, got a pos had a feeling then did a pg test and got a pos as well. But my count was around 200 at the time.
Given women have LH in their systems all month, the OPK's are made to be not overly sensitive so you only get a true pos when you are ovulating. So while OPK's do show pg, you'll get a pos on a pg test before an OPK.
I know it's hard, but relax and give it a few days. Stress can stop AF coming.

I would just buy internet cheapie pregnancy tests.. they are the same price as OPKs? I got a faint positive at 9dpo on ICs so I think they're alright! $6.95 for a 10 pack at Pregnancy Shop online...

i had a really bad experience with internet cheapies where I got a disappearing positive - like a full positive line after the test developed with time to show my partner before looking at it again after I put it down and realized it had gone. They usually come with my OPKs anyway so I'll be using them again anyway but I'm kinda cautious now.
I am wondering if an OPK line getting darker over time could be a sign of pregnancy? I've never had a positive OPK, i've had close-tos but never a test line darker than the control, though apparently that's common so they don't work for everyone.

Had heaps of left over opks so used them this pregnancy but they were always lighter than the hpt tests so hpt would show up much sooner. I only used opk once I was already confirmed preg to make sure the line was getting darker. Took to about 5- 6 weeks to get equal darkness lines on the opk. More likely to get a false pos from opk IMO given they can show light lines through your whole cycle. Maybe find a better brand of hpt ICs.

the other problem of course being that the hormone OPKs test for is generally present in the body to a greater or lesser extent constantly anyway . . . i am thinking lines getting progressively darker, the way they do leading up to O (in my experience anyway, I had a few faint lines that got darker then went away but never a full pos OPK) could be a sign of pregnancy? Obviously not definitively but if you're like me and a POAS addict, its an outlet at least

I used a leftover OPK to test (was actually trying to not test so had no HPT in the apt :-) ). It came up positive when I knew I couldn't be ovulating (either preg or period due) so from that I ran out and bought a HPK which was positive.

The only time I'd ever got a true (darker than the control line) positive on an opk was when I was pregnant and before I'd tested with a pregnancy test. This was a couple of days before my period was due too.
It certainly worked for me
