Hi Fresia,
Are u suffering heartburn? This is what I have find out from a website:
"Most likely. Many women experience heartburn for the first time during pregnancy and though it's common and harmless, it can be scary and painful. Heartburn (also called acid indigestion) is a burning sensation that often extends from the bottom of the breastbone to the lower throat. It's caused by both hormonal and physical changes in your body.
During pregnancy, the placenta produces the hormone progesterone, which relaxes the smooth muscles of the uterus. This hormone also relaxes the valve that separates the esophagus from the stomach, allowing gastric acids to seep back up the pipe, which causes that uncomfortable burning sensation. Progesterone also slows down the wavelike contractions of the stomach, making digestion sluggish. In later pregnancy, your growing baby crowds your abdominal cavity, slowing elimination and pushing up the stomach acids to cause heartburn.
Many women start getting heartburn and indigestion in the second half of pregnancy. Unfortunately, it usually comes and goes until your baby is born.
What can YOU do about it?
Though you may not be able to eliminate heartburn entirely, you can take some steps to minimize your discomfort:
Avoid foods and drinks that cause you gastrointestinal distress. The usual suspects are carbonated beverages, alcohol (which you should avoid anyway during pregnancy); caffeine; chocolate; high-acid foods like citrus fruits and juices, tomatoes, mustard, and vinegar; processed meats; mint products; and spicy, highly seasoned, fried, and fatty foods.
Don't eat big meals. Instead, eat several small meals throughout the day. Take your time eating, and chew thoroughly.
Avoid drinking large quantities of fluids during meals; you don't want to distend your stomach. (It's important to drink eight to 10 glasses of water daily during pregnancy, but drink it between meals.)
Eat your last meal no later than three hours before bedtime and wait at least an hour after meals before lying down
Sleep propped up with several pillows or elevate the head of your bed with a few books or a board. Gravity will help keep your stomach acids where they should be and aid your digestion.
Gain a sensible amount of weight and stay within the guidelines your healthcare provider suggests.
Wear loose, comfortable clothing; avoid any tightness around your waist and tummy.
Bend at the knees instead of at the waist.
Don't smoke (again, this is a habit you should break before getting pregnant).
An over-the-counter antacid that contains magnesium or calcium may ease discomfort, but check with your prenatal caregiver before taking one because some brands are high in sodium. You should also check in with your healthcare provider if none of these suggestions eliminates the problem. "
