Feeling like crap

I’m 7 weeks today... I’m starting to feel fat, bloated as hell, I’m getting small red pimple like crap on my chest which I didn’t have , my skin pigmentation is horrid I can’t use my retin-a micro gel for my acne scars and pigmentation I’m not liking this and I’m only 7 weeks I want to go see a dermatologist to get this I want to keep using retin-a it worked good on my skin and made me feel confident I am terrified of acne I had t before and it made me depressed I can’t afford to be depressed while pregnant I am feeling really down today and this chest pimple crap is really making me stress I hope to god this doesnt get worse and it shall pass :(
