Feeling bad about my body. Help!

I have been on a heath journey for over a year and successfully lost 30 lbs. I recently fell off/ stopped working out often and tracking for a few weeks and gained like 15 lbs. I felt like we weren’t going to conceive if I was in a calorie deficit, so I also kinda willingly stopped. Anyway… Then we found out I’m pregnant (5wks now) and I obviously am not going to diet. I feel so awful with this extra 15 lbs my pants aren’t fitting as well. Also my boobs are so big none of my bras fit. I know my body is going to change so much more and I feel like I’m really going to struggle with this. Any tips?
