Ovulation after miscarriage

Abbie
I miscarried at 11 weeks over the weekend and was admitted to hospital due to excessive blood loss. I just decided to do a pregnancy test to see whether it had gone back to negative yet (first time I've ever wished for just one line! - I don't intend on waiting to TTC again) and did an ovulation test at the same time as I had one in the pack. Pregnancy test is still positive, although second line is much lighter than when I was still pregnant. Ovulation test is definitely positive, test line a lot darker than control line. Is this due to hormones being all over the place from miscarriage or could I be ovulating this soon? I'm still having some slight spotting from miscarriage but I first started bleeding about 2 weeks ago. Any help appreciated as I have no idea!! Sorry to anyone going through a loss xxx
