I was wearing underwear (and pantyliner) and basketball pants. My bf was wearing underwear. We both dry humoed and he came. My pants get wet but not my underwear. Then i went home by bicycle (it means that my pants could soak into my underwear right?) for about 5 minutes. When i got home i found that my underwear had a little bit wet (on top of my pantyliner, although there s a gap between the top of my pantyliner and the wet part). I felt my underwear a littleeee bit kinda soak but not wet at all. I immediately took shower.I was on my 27 day of cycle, my due period is 8 days from there, my average cycle is 33 days. I took ovulation calculation on website and all of them said i was supposed to ovulate last week. Can his sperm gets into my vagina? What am i suppose to do? Should i took the plan b pill? This happened 2 days ago. Please answer me asap.
