My name is Nataly and I am only 18 yrs old. I live with my 20 year old boyfriend and we have been having unprotected sex for about 3 weeks straight. He has ejaculated inside of me every time we had sex. I have been having some insane abdominal pains, headaches, white milky like discharge and lower back pain. My periods have always been irregular so i never know when they are going to come. I have not had one yet this month but I think I may be pregnant. My mood swings have been outrageous. I really need some advice, please help!
