Placenta too close to Cervix and low fluid

I had my appointment today and I’m 33w2days. My doctor said my placenta is still too close to my cervix. I’m at 2.7cm and he likes it to be at 3cm. Has anybody else experienced this issue? Anything I can do to help naturally? He also mentioned that my fluid around the baby is at 7.1, he needs it to remain above 6. He mentioned sleeping on the side and drinking water helps with this and it increases naturally. Any past experience with this area? I’m awfully worried as I didn’t have any issues with my first so this is all new to me.
