I have been having sex since around september and sometimes its protected and sometimes it is not. I've easily taken the day after pill four times since I did not know that was harmful to take it so many times until recently. Before I took the pregnancy test I had a lot of pregnancy symptoms but the test turned out negative. I haven't had my period since september, can someone help me? i do not know what to do? During October I had brown discharge for about three days too. At times I do get some symptoms that occur while or before getting your period but no blood comes out.
