Gohan would be really surprised, but being the kind - hearted person he is, he would try to understand and help out. He could offer to train with them in a more gentle way to keep them fit during the pregnancy. Piccolo would be more of a silent observer, but still be there in case of any threats.
Vegeta might also feel a sense of pride and anticipation. He's been through a lot, and having a child with Bulma is a new chapter in his life. He could start training even harder to make sure he can protect his family, and at the same time, he might have some tender moments with Bulma where he shows his care in his own unique Saiyan way.
He could be initially dismissive. Vegeta has a high opinion of his own power, so when faced with a powerful female Saiyan, he might at first think she's not as strong as she seems. But as he sees her in action, he may start to respect her power. For example, if she's able to defeat some strong opponents he thought she couldn't handle.
