My last period was February 26, 2010-March 2, 2010. It was suppose to come back on March 30, 2010 but it didn't and my periods are regular w/o any months skipped. I have all the symptoms of being pregnant but i have taken 3-4 pregnancy tests only one had a very lite pink line for postive and the rest was negative. This morning April 10, 2010 i began to get a cramping feelig at the bottom of my stomach and my vagina seems very sore when i wipe it. Then there was this watery brown blood that was very lite on the tissue. So what should i do please have anyone experienced this before?? I'm supposed to be 6weeks pregnant right now with my calculations.....
