Can you get pregnant without any intercourse?

Ok so my boyfriend and I fooled around last Saturday. Here's what went down .. he fingered me and never did he once touch himself .. I gave him a ha****b and I didn't touch my self either ... he didn't c*m but he did pre-c*m ... we were also dry humping but I was wearing thin tights and panties and he was wearing boxer and basket ball shorts.. I didn't notice if it was wet or not .. then when he was fingering me he got a little to excited and stuck his penis out and touched me a little bit once on my clit but before he touched me he wiped his pre-c*m off and I stopped him really quick. Then my panties were wet from me and I went to change really fast .. I started to do research because I got a little scared and I read you can get pregnant in the silliest ways so I started stressing and plus I was in a fuse with my mom which made the stressing worse.. I also workout and do the Insanity plus hip hop abs workout and I've been on a pill name amox-clav because I had BV (STI) ... by the way my period came at the right time of the month and it's always usually a heavy flow with minor pains but 5 days after fooling around, I experienced one spotting except it was blood red then it never came back.. the next day (which is today) I had my period but only a little lighter then usual but with great pains and it lasted through out the whole day .. I'm really scared, I'm only 16 and I don't want a baby .. PLEASE ANSWER and don't be mean I know I should have been more careful .. sorry for being so graphic  :-(:'(
