I had unprotected sex with my partner on the 9th and 16th of Sept and now my period is 4 days late. We used the withdrawal method each time however but on the 9th, we had sex multiple times and even though he pulled out, he didnt pee in between. My CM is cloudy. I am barely getting cramps but I had my usual PMS symptoms (really emotional) all of last week. Is it possible that I'm pregnant? Should I take a test?
