Self confidence/anxiety

In need of some serious help:

My life got turned upside down some months ago and long story short I let myself go. In 5 months I gained 15 pounds. My clothes stopped fitting. I had never been one to workout in general, just had an active work life. But pretty much have been a couch potato for the past 6 months. I started working out for the first time in years right after New Years. Well I found out I was pregnant the beginning of January, litterally 3 days after I started working out. I’m 7 weeks. Since finding out I was pregnant just a few weeks ago I’ve had unmanageable hunger, and when I don’t have something in my stomach I get nauseated. I havnt been eating as bad as I had been for the last few months nor can I eat as much in a sitting but in just 3 weeks I’ve gained another 10 pounds.

I stopped working out when I realized I was pregnant because I was cramping a lot and super anxious about miscarriage from doing workouts that’s my body wasn’t at all used to.

I’m grateful to be pregnant don’t get me wrong but the thought of gaining a bunch of weight is terrifying me. I’m also super scared to start working out and hurting my baby when my body is the opposite of used to it. I’m having trouble being grateful and loving this baby because of all of my anxiety. I’m scared of my body turning into something so different, I’m scared of doing something wrong and hurting the baby, I’m scared of something being wrong with the baby.
