Okay so almost 3 weeks ago my boyfriend and I decided to try sex he tried putting the tip in multiple times but I was too small eventually he got the tip in but it was only in for a total of 15 seconds before slipping out, he did not ejaculate and there was no precum, we were unprotected and my period is now a week late and I am so stressed to the point where I am hardly eating and sleep is a maybe, I am very sure I was ovulating a few days ago and my cervical mucus was I fertile, my weight has decreased 3kg in 3 days I am not experiencing a single pregnancy symptom is it possible that I am pregnant???
