Weight gain/loss

This is my first pregnancy. It took us 11.5 years off ttc to reach this point and several fertility treatments. It finally happened with our second IVF transfer. I am 8 weeks today with twins. Anyway, before we started IVF, I was working on losing weight and lost almost 30lbs. However, taking all the meds during IVF treatment caused me to gain almost 20 of those lbs back. My fertility doc didn’t want us working out (I was working out 5-6 days a week doing beachbody workouts) because he feels it causes too much inflammation in the body and prevents pregnancy. So I stopped my workouts in March. Anyway, the point of this post is about Weight. I’d like to lose because I don’t want to be too big and not look pregnant or cause complication since I’m carrying twins. But I’m also concerned because I was told that for a healthy twin pregnancy for someone who’s BMI is greater than 30, gaining 35-55lbs is what the doc wants. I am terrified of gaining that much weight and never actually looking pregnant. I’ll do whatever it takes for these babies. But it does scare me. Anyone else feel the same way?
