Protective/Jealousy

Within these last few months of being pregnant, I have noticed I have been more protective of my husband (like I worry more about him especially at work since he does labor work). Is this normal?

I’ve also felt more jealous by seeing other young girls. I really don’t consider myself young because I’m closer to 30, but I can’t stand even if he notices another pretty girl. I’m about to have this baby and I know he loves me so much but I just don’t like him noticing them. I feel too a lot of them just priss by and don’t care how I feel and just want his attention. Any help?
