He use condom but I got pregnant

Helloo. .i just signed here to have someone to talk. Ive been seeing this guy for just a month, we had sex but I was really careful, I always asked him to use condom. I think its crazy but this morning I took a pregnancy test and it says im pregnant. I don't know what to do. I sent him a message but im sure he won't believe it. Im pretty sure that I never had sex with anyone. It was really wrong timing since Im just starting with doing some modelling and im enjoying it, I have an empty bank account cause my Aunt just got of the hospital after months of being treated. All I have on my mind right now is that I will keep it.
