I'm 23 years old. I have had really heavy periods for several years. My periods are like clockwork. Always the same, always at the same time, and always the same pms symptoms. This period started 3 days early (which was odd) and was incredibly light. It was really more spotting than anything else. So the first thing that goes to my head is "Am I pregnant?" To make matters worse I have been constantly tired. The past two days I have done nothing but sleep and today I'm forcing myself to stay awake to get things done. I have had a terrible backache and headache as well. I have been having unprotected sex with my fiancee for 2 years now and we have yet to have an oops... so I dont know if I'm nuts for thinking that this could mean I'm pregnant but after my period being so odd and then these other weird symptoms... I don't know what to think. Any body have a clue??? Anything would be greatly appreciated.
