What is the likelihood I am pregnant?

I am 15. So 3 weeks ago now I was fooling around with my ex boyfriend and he penetrated me probably about an inch (I told him not to and I stopped him). It was my first time, but like I said I didn't want to. it was for all of about 3 seconds, he didn t *** inside me but I have read a bout pre *** being an issue? he came on my stomach a bit after. Now I am really worried I could be pregnant? According to my period tracker this would have been a week after ovulation but I m not sure how accurate that is. My period came, about 3 days early but that isn t out of the ordinary. it was lighter than usual, though that could be from stress as I was stressing a lot about this the week before. There was one day when it was pretty heavy/ normal. So 2 weeks after I took a test and it was negative, but maybe it was too early. a couple days after my boobs started hurting which doesn t usually happen, I was getting mild cramps and lower back pain and now am getting headaches. I am not sure if this is just because I have been stressing about this so much, I have not been sleeping well either because I have been so worried. What are my chances? I will do another test when I can but I m not sure when I ll be able to buy one. I am also out of the country for 3 weeks now so can't do anything about it until I get home. Somebody please help? I am very scared and I just need peace of mind.
