My boyfriend and i were fooling around one day and this was a couple days after my period ended, he massaged me down there while i still had clothing on, and began bleeding a little that night, which stopped within a couple of hours. There was no genital contact, only fingers on clothing, massaging/rubbing genitals. I believe the bleeding is from the rubbing/massaging with my clothing still on, causing irritation and slight bleeding. However around a week later we were fooling around and I was on him and we were dry humping- there were four layers of clothing in between our genitals but he was aroused and I could feel him poking in a little. I do not know if he ejaculated, but it is now two/three weeks later from when we dry humped and my period is late, is it possible I am pregnant? Again there were four layers (underwear & jeans on both persons) and I could feel him poking in a little and my period is now late. I have never had any type of intercourse, only outercourse/dry humping (once). I have read multiple times that it is not possible to become pregnant this way & I have been through sex ed, but I am still worried, should I be concerned? Thank you.
