Advice

Ok here is the story; I was on the patch for a bout six to seven months I recently took it off late november early december of 2003 had a seven day period then the day after it was over had sex at least two to three times a day (i also had sex two times while on my period)each time after I would lay with my butt in the air and my head down hoping gravity would take its toll with the sperm. Immediately one week after my period was over I convinced myself I was pregnant thereafter the symptoms of pregnancy came. In that time frame I read as many books as I could seeing that theses symptoms were way to early to be having they amazingly stopped (wow). Anyways it is now feb. 6, and supposedly I was due for a period january 31, which I still to this day has not come,and the only symptom of preggie I have is fatigue and my pelvic region is alittle tender. The fatigue could most likely be from school or stressing about wanting to be preggie, and the pelvic region maybe from I don’t know, could I be pregnant or what is going on?
