Could I be pregnant

last night I took my birth control pill an hour and a half late which is really rare for me because i'm always on top of it same time every night. Then tonight I lost my virginity. we used a condom and we tested after with water and nothing leaked out. I'm worried there might of been a little bit of semen residue on my hands when we put the condom on. I didn't see any or feel any but I was touching him before we put it on and now im nervous. could i be pregnant? I would also like to note that my period ended tonight and I'm on the second pill in my pack:)
