Dry skin

I've noticed lately that my skin is really dry even after I apply lotion. Also the backs of my knees get itchy (kind of like if I have mosquito bites) ? I'm about 5 weeks along and trying to drink plenty of water. Any particular lotion that you ladies recommend? I'm currently using st. Ives
