Could I be pregant? I got fingered and there might have been sperm on his fingers I have symptoms.

Okay I'm 16 and Saturday the 26th me and my boyfriend went camping with his parents. They left and we were messing around. And I gave him a hand job well he didn't cum so we sat down and he stuck his hands down my pants and rubbed me through my under ware. I don't realy think I could get pregant from that right? So this Wednesday the 30th I was at his house I gave him a hand job and he just took over and jacked himself off well he didint come that time either. He washed his hands with soap and then fingered me under my clothes ,up my vagina. So I've been having stomach cramps and head aches and I'm tired and some white, stretchy, sticky discharge. I googled it and I think I'm pregant but it would be too soon for me to experice these signs right? I have never had sex and I have a job and It is summer vacation I stay up late and I am stressed. Could it be just stress and I have been sneezing. So cold maybe? Maybe I am just overreacting? Please reply I am very freaked out about this and very very nervous. I had my period on the 17th of may and I figured it out that I should get it on the 13th of June. Maybe it is just pms?
