I had sex and the condom broke the day after my period ended in the beginning of january, and then i got my period two weeks after thatin the end of january. About two weeks ago from today is when i got my period, and it was half as long as it usually is, and extremely light. My normal period is 8 days long, but it was only 4 days long this time, and on the first day, it was pink and slightly brownish. It got a bit heavier, on the third day it was more like a normal period because it was red, but still very light. The fourth day it was slightly red, but mainly pink. ive been very moody, and always tired and having headaches and constantly hungry. What is happening?
