Me and my girlfriend were playing with each other and

Patient: Me and my girlfriend were playing with each other and she was bit wet but when i entered my penis …i saw a liquid on my penis and i am certainly sure that i did not cum …still my gf took levonelle within 48 hours and she did pass her most fertility days. should i be worried about her pregnancy in case i cum …and i case i did not cum??? what if it is only a pre-cum?

Doctor:
