I had unprotected sex about two weeks into my cycle and took Next Choice. He "pulled out", but we were trying to be safe. My last period would have ended on the 17 or 18 of January and it is February 23 and I have no sign of a period. A couple weeks after taking Next Choice, my breasts were really sore and I experienced very painful stomach pains, but they went away after that. My body really rejects anything that isn't natural, so I wasn't very surprised when my period was late, but not I'm starting to worry. I'm also in a very stressful environment and with this added, I've been one huge wave of anxiety. What are the chances that I'm actually pregnant?
