So heres the updated situation. I am extrememly irregular when on my period as in I may not have my period for several months at a time. Anyway, a month ago I finish my period. I have unprotected sex a week later and again a week after that. 4 days ago I notice a pinkish discharge which later turned brownish red then the next morning I am bleeding. It was extremely heavy for a full day and then the next day it is light bleeding. The day after there is practically no bleeding but there is that pink discharge again. Now there isnt even that much happening. About 4 days before my "cycle" started I was exhausted, dizzy, nauseated, vommitting, frequent need to urinate and had very strange cramps in my stomach. I thought I was pregnant until I started bleeding. Now the bleeding has stopped I feel all those same symptoms as before. I don't have the tender breasts that everyone else describes when they are pregnant but does anyone think I might be pregnant cos I am really hoping for it.
