please help me😫😫

I have no idea whats going on and I really need advice. I am 23 and I only started getting acne after being pregnant with my son at 17. the pimples weren't really that bad. now after my daughter my skins is terrible!!!! it's not cystic acne or anything like that but I've always had pretty decent skin and now I feel not myself anymore. I just dont know what to use on my face. i used to not even have to used cleansers (just a tiny bit of baking soda in some water did the trick for me) and I'd be good to go. now nothing is working. I'm starting to reallllllly hate the skin I'm trapped in.
