i’m scared about pregnancy, help!!!

i got my last period in december, since then i’ve only gotten spotting. i have no symptoms that i know of but i was also recently sick and am stressed about a lot of things. the first reason why i could be pregnant is if this is possible, he had cum on his fingers then he put them inside me. another reason is he came inside me but he had a condom on. i’m extremely scared, and me and him recently broke up and i can’t get a test.

Any advice?
