coping with weight gain

I really could use some advice... 
I am only 7 weeks 5 days. 
The picture on the left is 2 weeks before I got pregnant and the one on the right today. I leave for vacation today and am having major anxiety about being in a swimsuit. In the past 2 years I made a MAJOR transformation and lost 55lbs. Best shape I've ever been in my entire life. I've stilled forced myself through pregnancy so far to keep up my normal gym routine- 5/6 days a week. I am really, really struggling. Don't get my wrong, super grateful to even be pregnant, but it is such a hard thing to deal with to have worked SOOOOO hard to get myself in shape and then to now be SO uncomfortable with my appearance. 
So I don't know if there's anyone out there who's been through something similar, but if you have any advice on how to deal, I want to hear it.
