Yes, My Girlfriend An I Had Protected Sex 2 Days

Yes, my girlfriend an I had protected sex 2 days ago and we also both lost our virginity. He started receiving stomach cramps right now and she believes that it may be her period because she starts very soon. There's no chance that it could be symptoms of pregnancy could it? Also, I'm not sure if I had pre cum on my hands when I put the condom on but the condom had spermicide.
