I am 19, on birth control pills for about 5 months. 2 or 3 weeks ago my boyfriend and I had unprotected sex he came inside of me without telling me, I was on top. I waited a day later to take emergency pill. Im expecting my period but no show. I had tan discharge for 2 or 3 days but no more. I had slight mild pains in abdomen and lower not painful but you could tell. I recently haven't been eating much, had a lost of appetite, lil sister asked have I been losing weight BC she could tell in my face. I've been lil stressed .. breast r slightly tender. Help me
