Q. I'm very much worried because of my late period. Hello, I hope I can get some help out here. I always had regular periods and never missed one. But this time, I have missed the date by 5 days. I am more confused as I am having the signs of periods but it does not come through. Also to add to my worry, I have been facing the symptoms of pregnancy. Well to be very honest, I had sex with my boy friend and we did not use condoms. I did realize that he ejaculated inside me. I am not really happy as I sincerely do not want to become pregnant now. Please help me. I am experiencing the following symptoms and hope someone can help me.Back ache, very tender breast, tired, cramps, more discharge than anytime, dizziness, nauseated. I would appreciate if someone can help me . I'm very much worried because of my late period.

A. Yes, I agree with mrfoot. next time you need to be more responsible to yourself, that's for your own sake.

what you need to do now is get yourself checked, you can use home pregnancy test, or just go to your doctor's practice. next time, I will suggest you and your boyfriend to use contraception methods (such as: condom, IUD, hormonal injection, pills, etc.)
