Any bariatric moms out there?

I am 1.5 years post op with the sleeve, 105 lbs down. I am 11w1d, and I've lost 5 lbs since I found out I was preggo. I worked out a lot previously but have had to stop due to sickness and exhaustion. Should I be worried about the weight loss or stack it up to muscle loss? Any moms further along have any suggestions for healthy weight gain, without giving in to cravings!!?? I want to be healthy and have a healthy baby!💜💙
