Okay so me and my bf always have unprotected sex but he always bes sure to pull out. Well he wanted to try cumming inside me one and he did couple of days later I had my period and we **** while on my period but didn't pull out at all thinking it would be fine, well past two weeks after my period ive been having a lot of symptoms of pregnancy. I took a test and it came out negative. COULD I STILL BE PREGNANT?
