Ovulation

I have a very regular 34 day cycle. I’m 3 days late ovulating, but this whole time while waiting for ovulation to come up, I’ve had pregnancy symptoms. I had af, but last time I found out I was pregnant I had what I thought was af, then after some very positive ovulation tests two weeks later, I took a pregnancy test, that confirmed my pregnancy. Sadly that pregnancy ended in miscarriage.

So my question is, if I was pregnant would my opks be positive? I wouldn’t care to just take a pregnancy test, but I only have the expensive FRER, and I really don’t wanna waste them.

I did take a first signal pregnancy test two days after my “af” but I got af nearly 6 days early.
