My gf and i took a shower together on december 20th, and im way taller than her. I didnt go inside her, my tip touched around her belly button, but when she stood on tip toes to kiss me, it was maybe an inch above her vagina. i didnt come, and i hadnt at all that day or the day before(i think), and this was six days after she started taking birth control, which her doc said would take a week to kick in. The water was hitting her front, so it was hitting where my erect penis was touching. She's freaking out cuz she thinks some sperm may have run down in pre-cum and gotten her pregnant, cuz now she's had these two weird headaches(though she said that birth control can change migraines, which she has) and was really nauseous for a lil while today after lunch(though she said at first she ate something that didnt agree with her stomach). This is the first time she's ever even remotely shown signs, and she said she got her period yesterday, but that it wasn't a "100% legit one" cuz of her birth control, which reduces her periods. Can someone please help me figure out if there is any risk? I love her, and want to help her relax. We haven't had any sex, just this incident have i come remotely near there. Please, someone respond ASAP.
