Possibly pregnant?

So 2 weeks ago I had my "period" it was a day of spotting.

I have had all negative tests but this would be my third and I just feel it I'm nauseous, tired, my belly is a little tight and I feel like my belly is rounder but can be bloating. 😭 I have had people asking me if I'm pregnant but all negative tests. Thoughts?

**Picture of belly/bloating, I'm very tiny so it's a big difference also never had spotting or anything with other kids**❤️
