Becoming a mom anxiety. Someone help!

Me and my husband are going to start TTC next month and I’ve wanted this for so long but all of a sudden I’m sooo scared. What if In a few years something happens and him and I don’t work out? Or what if after my body changes he starts to think differently about me? I love him so much and I know he loves me and doesn’t judge me. I think I’m just getting overwhelmed with all my fears. What if I’m a terrible mom and have no idea what the hell I’m doing and everyone sees it and wants to take my baby away from me. (My mom never raised any of her children so the fear may come from that). Are these all normal fears ? Will they go away? I don’t know what to do. I want to be a mommy so bad. I’m 25 and my husband is 30. I’m such an over thinker 🤦🏻‍♀️ we own a home, have jobs, savings, vehicles.
