Well this is my first time on here but I don't know what to do.. I am 22 years old, I have had my period since the 6th grade.. they have always been irregular but I always periods just different times in the month. Now I haven't had one since December. I'm not sure why. I'm thinking stress but my husband is thinking there is something wrong with me. Should I go to the doctor? And if so what type of doctor should I go to? I have no idea what to do.. I have taken pregnancy tests but they all say negative, I'm not on any kind of birth control. Actually me and my husband are trying to have a baby but I KNOW I'm not pregnant. He has had a vasectomy (I don't know how to spell) about 3 years ago. Please help me. I'm not sure if I should worry or not.

Just because he had a vasectomy doesn't mean you can't be pregnant. The little tubes that they snip, can grow back together. It is possible to get pregnant still. The chances are slim, but still possible. I would definitely go visit the doctor(an ob/gyn), as 4 months without a period is something that needs to be checked out. It could be stress, or any number of other things(including pregnancy) BUT its something that only your doctor can diagnose. Good luck, and best wishes
