QUESTION ABOUT THE PILL

Megan
I've been on the pill for a few weeks, on my first pack and the nausea and breast tenderness has died down, but whenever I eat anything I bloat like crazy and it's really uncomfortable. My lower abdomen feels heavy. What could I do to relieve this? Should I drink more water? Eat healthier and in smaller amounts? I HATE the way I feel.
Also my cervix has been extremely low and open (also firm) since I've started the pill, is that normal too?
