Hi. My boyfriend and I had dry sex with 3-4 layers of clothes between us. This was a week ago on April 19th. I got extremely worried although I heard it would not cause pregnancy so I took plan B after about 60 hours of it. We also consulted a few friends who have studied biology and five medical professionals about the matter. All have said the chances of me being pregnant are slim. I am aware that plan B causes menstrual like bleeding and have begun bleeding a little. Should I be worried about pregnancy? As far as we both know, there was only precum invovled and as far as I know, it did not soak through our clothes. I was told if it did, I would ahve felt it for sure. And all i felt was a little bit of myself but nothing else. And it only lasted abotu 3 minutes or so. after that he went to the bathroom to clean up a bit. Is there any need for concern?
