Ovulating after miscarriage but before period??

Hello ladies!

I found out I was pregnant 3/14 & by 3/25 my baby had not grown & I started to miscarry later that day. After numerous blood draws & lots of waiting my levels were considered negative for HCG as of 4/21. They said to wait until after my first period so I can start trying again (only said to wait so it’s easier to track and receive my Clomid

and follicle scans)

So I had a lot of slippery discharge today and decided to take 2 digital clear blue ovulation tests and they both said I was at peak fertility meaning to have sex within the next 48 hours.

is this normal? It’s been 4 weeks since I was told I had negative levels for HCG.
