I missed my period for almost 5 months, my boyfriend lives in other country so i know im not pregnant and im a virgin. Its my first time to miss my period, i freaked out and i thought that maybe there is something wrong with my reproductive system. Last august 1st i went to the Doctor and prescribed me a pill that is called Provera i took it every night after dinner for 5 days. My waiting period was Aug 6 to Aug 25. Because if ever i wont meet my waiting period they will do the rectal ultrasound if im not mistaken yeah and i got terrified so i exercise i eat right and i always eat on time to make sure i will meet my waiting period. And luckily i did. :)
