Help, Possible Teen Mom!

I'm turning 15 and tbh don't know what to do. So two weeks ago I went on a date with this guy, I was on my period and didn't think that I even had a chance of getting preggo cause I already have low fertility. We had sex, the condom broke and he accidentally came in me. A whole week after I started spotting, this has never happened to me before, then just an hr ago this water white liquid/discharge??? started to come out of me, like just running down my legs. Up until now I haven't been thinking about the chance of being preggo cause things like being nauseous is a constant and normal thing for me. But now I'm scared, please help...
