Cramps😫

So according to glow I was supposed to have ovulated 2 days ago, although I haven’t been taking any opks this month! But for last 5 days or so I’ve been having cramping and brown spotting for 2 of those days! I feel as if my period is about to start but it’s not due for atleast 10 days and after the spotting no sign of it since!

I had a chemical at end of December/start of January so maybe that’s why, maybe my bodies just not back to itself yet?

I don’t think it could be due to hormones from the pregnancy back then as I had the chemical very early on and the hcg went down very fast as it never got very high!

What do you’s think?
