if you have been having unprotected sex wtih your boyfriend for the past 10 months how come in your last post you talk about "I'm 18 and experienced my first with my boy freind three months back" and that was in novemeber?
your boyfriend is NOT "concious about how a fertilization happens" he DOESNT need to ejaculate for you to get pregnant
it does sound like a uti
but if he is not ejaculating, then why are you concerned as to why you DIDNT get pregnant? because clearly you two dont want to get pregnant as him pulling out
beach23 is right.....with the pain during and after urination and blood, it most likely is a urniary tract infection.......they'll test your urine and put you on antibiotics if that's what it is.
sounds like you could possibly have a urinary tract infection, or some other kind of infection. you should probably get in to see your dr just to make sure. good luck.
