It is Day 7, after I had unprotected sex with my boyfriend,he said he pulled out way before he ejaculated,I felt it on the bed,I'm just concerned so my mom went and got me the Next Choice One-Dosage Pill and I took it three days after the sex had happened. It is Day 4 at 2:14 a.m after I took the pill and the only symptoms are my abdomens a little sore,kind of cramping and my lower back was hurting earlier today. I'm very paranoid is this good or not??
