Hello, I am 25 yrs old and I have 1 child who is 4. All through h.s. my periods were irregular and  i wouldn't have one every month.(let's say I had about 7 per yr).. After having my son I was on birth control and i switched from the mirena to the patch. After i got the mirena taken out I was suppose to start the patch after my first period but it never came, and this was about 8 months ago. My fiance' and I haven't really been "trying" to have another baby but we haven't been using protection either.(we would be happy if we did) But it's just strange to me that by now im not either pregnant or my period hasn't come yet. Has this happened to anyone else?
