<s>[INST] Hi me and my  girlfriend was messing about and i had a tiny bit of precum on end of my penis. I  was trying to insert it into her vagina but it didnt go in. The tip of my penis was just rubbing her vagina so could she be pregnant? And i have Mercilon so could i use it for morning after pill to stop the baby? [/INST] dear Sir, there is a tiny possibility that she gets pregnant so it is bettet to use the morning after pill to eliminate any chance of getting pregnant </s>
