Help!?

Destiny • 👼🏻 2020 👼🏻 2024 Rainbow 🌈 baby girl born 11/3/2021 at 5:59pm 7 lbs 9oz 19 3/4 in.

I had a chemical pregnancy on feb18th and basically had a normal length af for 7 days. My cycles last about 30-35 days so I thought my ovulation was around cycle day 16/17 and I waited two weeks to test for HCG and they’re coming back negative. My right ovary has been aching so I take an OPK too and now this. I’m confused.
