It's a little early to be experiencing rib pain as the uterus is still not pushing into the rib cage. Along with the other symptoms it could be a D3 deficiency and should be discussed with your doctor.

I slept on left side because my right side is paining very much I cannot take right side position.. ,

drink warm water,look into your sleeping position use pillows.check n change bra size. if you wish join prenatal yoga.
