Ovulation after mc

I would not trust that this is ovulation. It took me 5-6 weeks with my 3 losses to test negative

I highly doubt this is ovulation. Your body still has to recover and your cycle has to find some normalcy. I miscarried in December and was still testing positive in April.

Pregnancy hormones can stay in your body for up to 3 weeks after a miscarriage. If you still get a positive pregnancy test after 3 weeks you need to go so they can do blood test as there may be retained tissue from the miscarriage left over x

Agree. Pregnancy tests usually detect hcg>25. Between 5 and 25 they can get picked up by OPKs. If you saw a surge, peak and drop you might be ovulating. But if it's a constant shade across many days, it's highly likely that it's lingering HCG. Mine's 7 weeks post D&C n I still see lingering HCG.

Just for an alternative opinion, I ovulated on CD20 after my miscarriage at 6 weeks (CD1 being day 1 of bleeding and miscarriage).
I conceived on that cycle and pregnancy was successful!
I had been testing my hcg lines down and continuously testing OPKs to try and identify my peak. So maybe keep testing for a few days to see if you can see a drop in LH x
