I usually have a 35 - 36 day cycle on my period. This last one I had was 29 day cycle, I woke up to cramps, no blood. An hour later I have brown blood, and for the rest of the day it was like that as well. The entire period was only 5 days which I usually have a 9 day period. The entire period was brown and one day there was a little bit of reddish/ pink blood. After my period ended I have been having severe nausea, dizziness, diarrhea, and headaches. Also I had a fever for two days. I am curious as to what is going on with my body? If I could be pregnant? My husband and I have been TTC for 3 years now after our MC.
