    What causes missed periods?
    stemnena posted:
    First of all the past 3 months I have hardly had a period at all. I have also been really stress with personal things in my life. I take birth control pills, on time everyday. In December I took some samples I had left from visiting my doctor, but I didn't really look at the date on them until after I already took them. They had expired on May 2012. The reason I took them was because I didn't really have the money to get my birth controls because the price has gone up and at that time I didn't really have the money for them and knew I had those samples. In January my period was just a little lite bleeding and that was all. I went and brought my birth control pills and have taken them. And now I am 5 day late of having my period. Before those 3 months I was always on time. I have taken a couple of pregnancy test (different brands and different ones) and they have all came back negative. I don't have an signs really of being pregnant but it is one of my fears when my period never comes. I also started taking bacterial medicine on Friday, since I have an infected toe and trying to clear it up. I'm just trying to figure out what sometimes cause people to miss a period and that. And if maybe age has anything to do with it. I just turned 28 in December. I have been taking birth control since I have been 18. I was on the patch for awhile, loved it. But then I wanted to switch to a pill and I have been on the pill for 3 or 4 years now. I would love some insight. Thanks!
