My girlfriend missed her period in January before we had done anything sexual so this was a random missed period , but she also missed her feburary period, I dont know when in a month she gets her periods but on the 19/2/13 my penis touched the outside of her panties, I don't know if there was precum on it or not though, is she pregnant, she doesn't want to take a test, and she is still in puberty so the missed periods coul be because of that, but I'm still really worried
