My girlfriend and I were fooling around yesterday, this was the first time we had seen each other completely nude and she got very excited by it and started to thrust against me (she was completely nude I still had some clothes on) and I'm unsure my penis which was covered in Precum touched her vagina (it could never have went inside because I still had underwear on but the Precum had seeped through) about 5-6 mins after this I fingered her, again I could have had some Precum on my fingers but it was most likely dry but still, how high is our risk of pregnancy (her period is due around 30th - 10th of each month(s) and today was the 21st)
Your chances of her getting pregnant just by being exposed to "second hand" pre cum are slim. If you are going to continue to have intercourse though, make sure she is on birth control, and is taking/using it properly, and always use a condom. At least until you are 100% sure you want to start a family. Trust me, if you're not ready, parenthood can be a scary path.
