Um well YES! But mostly because there are two in there for me. I measure full term and I have 11 weeks til my DD. Ugh!
Prilosec is my best friend for heartburn. Once in the morning and I am good the rest of the day.
Also you might try taking Calcium/Magnesium vitamins. They help with HB and leg cramps. I take 2-3 a day usually before bed. Also helps with sleep.
Amazingly I am sleeping okay besides having to pee every 2 hours or less. I have 5 pillows. 1 between my knees, behind my back, 1 is front and 2 under my head. It takes some arranging but I can get comfy.
