Acne during pregnancy

I’ve always been lucky and had pretty good skin so far and nothing more than 1 or 2 pimples at a time that would go away after a few days. Well I’m 15 weeks now and ever since I got pregnant I’ve been breaking out really badly. I have a good skincare routine and I’ve never had any issues with any of the products I use.

Now a few days ago I got a really big cystic pimple on my face and it’s so swollen to the point where it hurts really badly to even open my mouth. Does anyone know any DIY ways to get rid of cystic pimples fast or any products that are safe to use while pregnant?
