My boyfriend and I finally decided to have sex; we were both virgins. He put on a condom, and went inside of me but it was too difficult to enter because I was so tight. Later, we tried again but without a condom. I was on top, he just entered once, and we didn't really enage in sexual activity; we just wanted to see if it would fit. He pulled out right after that. He didn't cum, or let out precum since we didn't really engage in sex ... But now I feel like I'm having pregnancy symptoms, and my period is almost a week late. Could this be a phantom pregnancy, or am I pregnant?
