Help ?!

Ladies,

I had a MC at 6 weeks back early December . We have been TTC since. I got a 2.5 day period (what I thought was a period January 28-30th. I didn’t have anything for CM 31-3rd of February but this morning spotted brown. I now feel crampy, my boobs are killing me and just bloated ?!?? I feel pregnant and I know it’s not in my mind bc I was looking forward to focusing on conceiving this month 😅 could I be pregnant ?!??? I took a test Saturday and it was negative
