I had unprotected sex on the 31st, but he pulled out way before he finished, and was supposed to start my period that Wednesday. It's Friday and I still haven't started. Im always right on time. I have been stressing a lot about it. And Since he did not ejaculate in me, the possibility of getting pregnant is very unlikely. I would like to take a test, but it hasn't been long enough since we had sex to take a test to have it be accurate. How many days should I wait to test, and is it even worth it to test since pregnancy is so unlikely?
