Exercise?

Hello Ladies?! Hope you all are doing well.

Should I exercise while pregnant?

I am 14 weeks and feel very good but to be honest I dont want to gain so much wait so I have been taking care of what I eat.

What creams did yall use for stretch marks? I started the strech marks with almond butter or something like that and in the rest of my skin just regular lotion to take care of my skin. I cleanse my face every morning and I am trying my best to take care of my body but I need advice!!
