Hello. Last Week Me And My Girlfriend Had Engaged In

Hello.
Last week me and my girlfriend had engaged in sexual behavior including masturbation. But there was no penetration however. I had ejaculated on myself and cleaned up after I think I got most of the semen off without getting any on my hands but I have no idea. She was a virgin and I had broken her hymen fingering her prior to this. After she wanted me to check if the bleeding was still occurring. I stuck my finger inside to check but there was no bleeding. But I didn't was my hands after wiping up. should I be worried about her being pregnant?
