Advice on what I should do

So Saturday i lost my virginity to a guy I’ve been on and off with for about 1 year and 4 months well yes it was my first time with him but unfortunately i didn’t feel pleased mind you i didn’t even notice when he put it in and midway through having sex i realized he didn’t have a condom so I ask him to stop but then he only lasted like 3 min our less idk if I should be worried about being pregnant but I did ask him if he cummed in me but he said no
