Well I Had Sex (unprotected) With My Boyfreind On Saturday.. It Was Me And My Boyfriends 2nd Time In Like A Month And A Half, Maybe Longer.. But Sunday I Was Okay.. Then Late Sunday Night/Early Monday Morning I Started Having To Urinate Very Bad And My Stomach Hurt Very Bad. ThereWas A Sharp Pain After I Got Done And Light Blood On The Tissue That Is A Pinkish Color.. I Believe It Is A UTI, But I Am Afraid That It Is Something Else.. Help, Pleasee ?!
