ovulation test detect pregnancy | Mumsnet (2024)

It is only if you have a really strong line, as dark as the control line, that it can indicate pregnancy.

The ovulation hormone is always in our system so there will always be a faint line on the OPKs whether you are ovulating or not.

The ovulation and pregnancy hormones are very similar and OPKs detect both as they can't differentiate between the two. If you get a very dark line on an OPK when your period is due then it can indicate that there a high level of HCG in the urine.

hi themumfairy, I've had interesting opks at 12 dpo, resulting in bfn and more recently a bpd (6+4 today ). For me they were bc different.

I got faint bpf at 10dpo with frer, ic, and a faint line on an opk (i like to poss, can you tell?). By 12dpo the opk test results were v strong, my ovaries would have been proud if they hadn't already done their job. The test line much darker than control line, and much stronger than I'd seen over the last 6 months of ttc.

However, I have had cycles where I've had 2nd lines on opks after ov, sometimes just quite faint test lines but also sometimes more than one apparent LH surge. I did have a weird long cycle where af was a week late and and at 12/14 dpo was getting faint opk results but no bpf.

opks can show bpfs as the LH hormone they test for is molecularly similar to pregnancy test hormone, but absolutely no guarentee. Test again with a proper test and let us know how you get on. good luck!

When I was pg I tested using and OPK as I was testing everyday.
The line was darker than the control line. Just like a positive OPK.

I got my 'BFP' as a result of peeing on an OPK because I had ran out of I.C pregnancy tests as I was testing twice a day

I had no idea OPK's could detect pregnancy and just pee'd on one for something to do When I got a really strong positive I was really confused as to why my body was ovulating when my period was due and it was a mumsnetters that explained about the pregnancy detection capabilities of OPK's.

I bolted to my nearest supermarket to buy a branded pregnancy test and I got an instant BFP

Yes OPK's can detect pregnancy, but no I don't think you're pregnant (based on the faint OPK line only).

I almost always have 2 lines on OPK's, which is totally normal. The test line is always very faint until I OV and then it's dark dark dark.

It is normal to get a second LH surge just before your period too. So even a near positive result still means nothing! A pregnancy test will show faint positive before you get a strong positive on LH strip!

Hope that you get your positive hpt soon instead!
