Breast discomfort is completely normal during pregnancy. They are undergoing alot of changes getting ready to produce milk for your little one. As for the discharge as long as it doesn't have a strange odour it is perfectly norm. As for movements depending on whether you have an anterior or posterior placenta that can affect feeling the kicks. If you are worried about the baby I recco mend an at home Doppler to monitor babies heartbeat and movements. As for what to eat just try e atting healthy. Oatmeal is good, boiled eggs, nuts and seeds, fruits and vegetables, meat, fish.etc. And your doctor probably already told you to take a prenatal vitamin as well. I wish you a healthy, happy remainder of your pregnancy.
