On March 14th, my boyfriend and I were dry humping. I was wearing underwear and small cotton shorts, and he was wearing briefs and sweatpants. During all of this, I dont know if he pre-ejaculated. All I know is that I was wet. After a bit, he ejaculated and I had a wet spot on my shorts. I checked my underwear to check, but since I was also wet. So I couldn't tell if anything got on my underwear. My last period started March 3rd. Around the 26th or 27th, I saw little blood in my discharge. I thought my period was going to start early, but I was wrong. My actual period was supposed to start April 3rd and now I'm 4 days late for my period. For the past two days, I've been feeling nausea. I also had diarrhea and been very gassy. I'm scared if pregnancy could be possible. I'm hoping that my period is late. I read on many sites that pregnancy is possible. In my case, is pregnancy remotely possible?
