Ovulation after miscarriage

Brianna • ttc baby #2👩🏼‍🍼

I had a miscarriage at 8 weeks on Feb 22. I stopped bleeding on march 2 or 3rd on March 7 I had lighting cramping,headache and just felt like I do when I ovulate. I also had a little spotting just once on March 7. I’m wondering if my hcg looks negative enough to ovulate ? My ovulation test before this was lighter. And after that test was lighter again this morning.. today is 2 weeks since my MC.. Someone help me or just tell me your experience please
