Me and my boyfriend had unprotected sex about 2 weeks ago but he pulled it out after like 3 thrusts. Can pre-cm get you pregnant ? I was supposed to have my period 10 days ago and its still haven't came, I'm very nervous. Also, I did some research and apparently change of routine, over exercising and stress can delay your period and I didn't start dancing for almost 2-4 hours everyday until the end of July plus I am also stressed because of my upcoming test. I was also so anxious and stressed because I keep thinking I'm pregnant. I'm assuming these are the reasons why I missed period but I am also nervous that I might be pregnant. Please help.
