I have not had a period in over 7 weeks. The last normal period was about 10 weeks ago. I had a previous pregnancy where i found out i was pregnant 12 weeks along. The only way i knew was with a blood test. The urine teasts all came back negative. I've taken 7 home pregnancy tests,had a labratory urine test done and still i have a negative result with no period. I have recently taken a blood test, and hopefully i will know the result soon. If i am not pregnant what could the problem be? I had cancer cells removed 9years agoand have regular pep tests. I also had a pelvic exam done and still no answer to what is wrong. Whay do think? Am i pregnant or is there something else wrong? I have irritability no period, itchy breasts, tired alot,increase in appitite, and for the last couple of days i've had cramping and tightness in my pelvic area and in the vagina. If I push lightly on my abdominal area i feel like i need to p. Plus i have tenderness on the sides of my abdominal.

I do not know why you have not had a period. I suggest you see a gynecologist or your family doctor. You need to have a pregnancy test and probably a pelvic examination. I would not want to guesss what your symptoms mean without having examined you.
