I think I may be pregnant. My last period was due Sunday April 20th. I have been experiencing symptoms of pregnancy, sore breasts, nausea, head and back aches, and fatigue but they all could be signs of PMS or my anxiety as well. I took two home pregnancy test last night and they were both negative however, my girlfriend had her son last month and she had 4 negative results when she was infact pregnant. Earlier today when I went to the bathroom I had a very little bit of red blood only when I wiped. However, my periods are never ever light, and always come all at once, when i went to the bathroom again there was no blood. I thought this may be a sign that my period was just being very unusual, however I remembered that my fiance and I had rough intercourse last night. Sometimes if we have rough intercourse it stimulates my body and i get my period the day after or so, but now I'm concerened that it may have just been a ruptured vessel from having rough sex since there was such little blood and I have never experienced a light period like this one. I know my cycle is exact because i was on the birth control Orthocyclen, however, I was hospitalized 2 months ago due to diabetic problems and had to stop taking the pills, I didn't start re-taking them yet, and did have unprotected sex with my fiance. I was wondering how possible it is that I really am pregnant and if it is worth going to the doctors to get a blood test or if I should just treat the slight bleeding as a period?
