Okay so heres what im going through. My last period was on the 11/23/12, and i have a cycle of 33 days. On the 11/1 , 11/12 , and 11/14 i had unprotected sex.. He cam inside me on the 12th about 4 times and on the 14th once.... On friday(12/7) i started having really bad cramps that i never had before and i'm still having them. I took pregnancy test on that day at a clinc but it came out negative. Right now im really confused because i always have unprotected sex and did for about four months and ever since than my periods where very different than usual. I did have my period on the 23rd but it only lasted for 3 days and it was very light. I only used about 1 tampon a day... I did spot five days after my "period".. I also noticed that my stomach is bloated and when i press on it. Feels tight inside (not normal for me) and when i wake up it feels hard but when i use the bathroom. It just gets a little smaller. My breasts hurt and there are little bumps that werent there before. The nurse at the clinc told me to wait until i miss my period to take another test but its not due until dec 25-26, so is there anything else i could do?? Could this be some kind of stomach cancer (and i cant go to doc office now because my health insurence is not active and i cant offered). I'm hoping that im pregnant because if im not. Something is seriously wrong with me. Hope i didnt make it confusing. But please anything would be helpful!! What should i do? But please dont tell me pregnancy test.
