"i switched from ortho tri-cyclen to microgestin three months ago. i did not like the side effects i had with my old pill. i took it for a year and decided to switch. the first month i got my period as scheduled. i missed it completely the second month. i am hoping to have a period this month. i think it&#039;s silly for a woman to continuously have to take pregnancy tests while on the pill, i take it so i don&#039;t have to worry about it. so i don&#039;t know that i like this pill either. i am wondering how many woman do not have a period while on this pill, when i called my doctor he said it was &quot;normal&quot;."
