Worried

Hello. I have a friend who recently had sex for the first time. It wasn’t even really sex honestly she said he just went in for a few minuets then they stopped. He didn’t cum and before they started he wiped off the precum. They were both really worried after and she wanted to ask someone but she was too scared so I’m doing it for her.

Bottom line: he went in dry and they’re worried some cum leaked out while he was in

He masterbated the night before but he peed at least 5 times after that. He wiped off the precum and he only thrusted a few times then they stopped. Her period just ended the day before. Could she be pregnant?
