On Valentines day, my boyfriend & I had sex. He pulled out, but after he was done, he stuck the tip back in & back out. He came "down there" & I wiped it off when we were done, but not all because I could tell there was some still in me. About 30 minutes later we almost had sex again, he put it in, but we never did have sex a second time. I know that I will probably get pregnant, but could I have symptoms this early? I'm constipated, very tired, & urinate a lot.
