I have not had a period cycle since my youngest son age 5 was about two and a half is it still possible to even get pregnant without having a period cycle? The doctors think it's stress related that I've been to. I don't know what to do, I don't even know if its possible to conceive when you don't have a period cycle. Does anyone have any input on this issue or knowledge better yet? I'm not getting any younger I am 35 and I fear that I'll never be able to conceive a third child.. Does anyone have any input on this issue or knowledge better yet? Any input would be greatly appreciated
