TERRIFIED to be a momma

I'm a big over thinker I am SUCH a creature of habit and me and my husband are insanely comfy right now we have such a routine, go out whenever we want(which isn't a lot ) this pregnancy is WANTED although it happened a bit sooner than planned. We are both excited of course, but I have these moments where I am terrified . I keep thinking I'm not gonna be a good mom, that I'll never get my figure back, never have fun again... PLEASE take it easy on me , I am NOT saying I don't want this baby I'm just an anxious mess on a regular day and add the pregnancy and all the changes that come with that. I'm just really looking for advice and personal experiences I guess. Have any of you guys ever felt like this ? Am I already a bad mom for being so unsure ? 🥲
