Weight Loss while pregnant?

Caitlyn • Ckreklewich♡
I gained 25 lbs from cervical cancer treatments finished them 2 months ago. I'm currently sitting at 185 and felt my best at 160. I wanted to lose the 25 lbs so when I got pregnant or would be fine gaining it.. I'm now currently 6 weeks pregnant. I can't drop a lbs. Even with my still weight training and eating healthy.. I'm upset because I don't want to hit 200lbs... idk what to do. Any advice?
