So first off I'm 25 married on because and have a 2 year old. About a week before I was supposed to start my period I had a brown discharge which has never happened to me before. It lasted about 3 days. Then nothing.. no pms(which for me is very noticeable) and no period. Its now about 3 weeks late. Ive taken 4 first response pregnancy tests all being negative. I've felt sick like I did with my first pregnancy, have had headaches, and bloating. Any idea what could be going on?

We could speculate on it, but we wouldn't be able to provide you with an accurate answer. If you are experiencing symptoms that are causing you concern, you should see a doctor just to be safe. He/She can do a pregnancy test while you are there to put your mind at ease. IF you are taking the tests correctly, the likelihood that you are pregnant is small, but a doctor could tell you for sure, and make sure that your symptoms aren't the sign of a more serious problem
