Okay so I had sex last Thursday and we had it unprotected for a minute, nothing bad. I had it again this Thursday but I was ovulating, (high chance of pregnancy)... we did not use a condom Some of the time and I got scared that we didn't use one an hour after he already ejaculated. We went to cvs and got a morning after pill and I took it asap. I'm getting side effects such as tiredness and cramps and back aches, am I pregnant ?
