Worried about my weight

I am at 8w2d and feeling really uncomfortable about my weight. I quit smoking in march and gained 10 lbs, previous to that I was approx 10-15 lbs above where I was a year prior. Last week I managed to put on 4lbs.

I'm feeling really down. I look like I'm 6 months pregnant when really I'm only 2. Is there a safe way to lose weight? Can I doubt calories at this point without harming the baby? Thank you in advance.
