My period is regular but my last normal period was 7th of Jan 2011 im between a 28-30 day cycle. I have taken 6 home pregnancy tests at different times and they are all negative. I have no pregnancy symptoms. I am worried that it could be something else such as PID, ovarian cyst ( i did have small cyst on my ovaries the last time i was at my gynea he told me it was nothing to worry about). My next apointment with my gynea is on the 1st of March 2011. I just need to know what could have casued me to miss me peiod and is pregnancy an option?
