My period is 3 weeks late and iv been having unprotected sex with my boyfriend of 3 years for 7 months. Iv never missed a period and i dont have ANY pregnancy symptoms. Nothing at all. Although round about when my period was due i did get period pains but went a little later and Usually before my period my boobs get sore but that didnt happen. Iv took 3 pregnancy tests but were the cheap ones out of poundland and they came back negative. I have been to my doctors and they gave me a pregnancy test and that cane back negative. Went back to my doctors and they refused to give me a blood test and said that you cant tell if your pregnant by taking blood. They refused point blank to give me a blood test. I dont feel pregnant and im not under any stress at all but i really dont know what to do :/ any ideas :) Thanks
