I have been feeling pregnant lately but am so confused. My last normal cycle was 10/15. I had a negative blood test about 2 weeks ago. I got what I thought was my period on 12/25 finally but now I'm wondering if it could be implantation? My periods are always heavy with clots and cramping. This time it was only when I wiped and a tiny amount on pad, mostly a brown color and no clots. I had zero cramping. It ended 12/28 and I have been extremely nauseated ever since. Anyone have a period or IB like this?
