My girlfriend and me had unprotected sex at 11 in the morning, I came inside her, then we rush to CVS and buy Aftera and my gf took it at around 12. About 30 minute later, we have unprotected sex again, thinking we just take the Aftera, then it will be ok if doing it within 1 hour of taking the pill. My girlfriend is ovulating today, and she is feeling pain on her lower tummy after about 4 hours of taking the pills. What do I need to do? Should I buy her another Aftera ? And how high is the chance of having pregnance?
