Skin issues

E

So my skin has been mostly clear since I had my first child. Now I'm 21 weeks pregnant with my 2nd and I have these annoying little pimples that show up on my cheeks almost daily. Why?! I'm 32 so I had mostly switched to an anti aging skin care routine but now I'm thinking I need to use something different. Is it even worth it or will nothing really fix this until after pregnancy? Thanks!
