Scared...pls help

I had sex with my boyfriend on Sunday (night). I wasn’t on my fertile days. We used condom and he didn’t come inside me but i think he had some cum from before on his fingers and he did finger me...(he says that he is 99% there wasn’t any cum) I am very anxious and paranoid person, and when today (Tuesday) I saw some weird discharge I immediately burst into tears... Discharge was light pink and there wasn’t much of it... I think I don’t have any other symptom (yet?). Please help. Is it impossible to have any pregnancy symptom this early? Is this only my stress and maybe UTI...? I am so stressed and don’t know what to think
