Pregnancy or?

About 3 weeks ago, I had unprotected sex and he came inside. I used no form of birth control. A week after that, I noticed “spotting” so I figured it was my period. But it stopped after two days. I haven’t noticed anything after that.

About two weeks ago, I went to the doctors and ended up having a UTI. I haven’t really noticed much pregnancy symptoms. Just headaches, going to pee more, food cravings, mood swings, late period. But that could be for many reasons.

I’ve taken multiple of urine pregnancy tests and they’ve all came back negative.

I took a blood test and that came back negative too.
