Possibly pregnant after Miscarriage?

Jenee

I had a miscarriage Nov. 20. The bleeding stopped Nov. 28. I started trying for another baby after the bleeding stopped.

I had spotting Dec.23. I have been super gassy and have had cramps on and off for about a week or 2. I havent had a period since my miscarriage either.

I also have had heavy cm for a few days.

Ive heard you can get pregnant soon after a miscarriage and Ive also heard the opposite.

Ive taken several tests and they were all negative. The last test I took was Dec. 23 or 24.

Could I still be pregnant?
