Hey, I am 21 and lately I am scared that I may be pregnant. My last period was on Dec. 18 and my boyfriend and I lost our virginity around the end of Dec 2012. Don't have the greatest memory so I missed a few pills here and there. Also he used a condom but broke a few of them. I have missed my period and week or so later I have this really light period with brown clots that lasted for 3 days only. Taken 3 preg test and all came back neg. Today did the blood test, and the doctor hasn't called me back and was kinda rude to me saying it is just a period. Should I be worried or no? Help please :(
