*TW*ED during pregnancy

As a teen and into my 20s I struggled with EDs, I went through 2 pregnancies only gaining 10-15lbs. After I got divorced I got a lot better, and actually was a little over weight at one point. When I reached the "overweight" threshold I fell back into my ED patterns until my SO caught on and helped me calm down, that Jan 21, I lost 20lbs in less than a month, so back to a "healthy weight. Since then I've been trying to eat healthy and work out, without going crazy. Now I'm pregnant and I'm falling hard again. I'm terrified to gain weight and have even purged a fee times. I feel so guilty, and I'm trying my best to not be this way, but I'm struggling. I've gotten back into the habit of weighing myself every day and and calorie tracking like crazy. I know I need to stop, but its so hard, I hate being this way. I want to talk to my doctor about it at my next appointment, but my SO will be there and I don't want to bring it up in front of him I'm too ashamed.
