New member here and worried about this first question. My gf's fertile window supposed to be from 17 to 23/08. Last night 18, we were playing with condom, (in any case not inside vagina just out) we are worried to consider on buying the day after pill cause when i took the comdon out it had moved to the tip, and wonder if some sperm could have gone out from the back and somehow get inside. We are concerned about whether it has entered vagina or not and how high could be the risk of getting pregnant. Please help. Thanks in advance!
