That happened to me too. About a year after I had my last daughter my period just stopped, and I wasnt pregnant. I hadnt had a period in 5 months and went to the clinic and they put me on birth control, after 2 months of taking them I finally started having one again. Now im afraid to stop because I dont know if I will still have a period if im not on them, I have been taking them for 2 yrs now. When I get my check up every yr everything is good, so im not sure what is going on.
Hopefully they find what ever is going on, and they will probably put you on birth control, unless you are wanting to get pregnant.
