Weight gain self-consciousness

Hey ladies!

So I'm 34 weeks and am roughly 45 lbs up. I know that I'm growing a human being, I know that it's silly or not important at this stage. I have been told to not feel self conscious and to just keep focusing on eating healthier foods and try to walk/ do yoga. I was doing that, but I had some issues and my doctor told me to be down and rest for a few days. I'm scared about the 4th trimester already and how I am going to get back to where I was... I have a thyroid disorder which causes weightloss to be extremely difficult for me.

I have always worried about and watched my physique, was a personal trainer for a while. Before I got pregnant, I had an injury and was unable to workout for months. Then I got pregnant and was still recovering so I was not able to workout. Now my injury is healed, but I'm far enough along that I can't do what I was doing, and even light walking (with belly band support) or a yoga session causes sharp pain and sometimes brings on braxton hicks.

Does anyone else feel extremely selfconcious or worried? I hope im not alone...

Apologies for the dirty mirror and background!
