Ovulation days after miscarriage ?!?

Ok. I need some help! I’ve been taking ovulation tests after the bleeding stopped after miscarrying. Yesterday and the day before were both negative (aka low LH). I just took one an hour ago and all of a sudden it says high!! 🤯

Has anyone ever heard of that?!?!

LOL I’m not complaining but I’m just curious. I miscarried at 4 weeks. So it was really really early. So I figured it would be quick but whoa! I know that ovulation can occur at anytime after miscarriage and it varies. But I’m curious if anyone else has experienced this???
