Pregnancy By Weeks – Week 14

14 weeks is the beginning of the second trimester. The baby is about 3 ½ inches and 1-2 ounces. It is the size of your fist. The baby continues to move although you probably cannot feel it yet. The baby is beginning to grow hair on it body. This hair is fine and soft and called lanugo. It helps to keep the baby warm. At 14 weeks the baby has difficulty with temperature regulation; the lanugo helps with retaining heat.

There is a common myth that hairy babies cause heartburn. This is not true, pregnancy causes heart burn. The pregnancy hormones act on the woman’s gastrointestinal tract in several ways. The gastric emptying time is lengthened. This means that it takes a longer time for food and digestive juices to leave the stomach. The pregnancy hormones also decrease the strength of the lower esophageal sphincter. This is the muscle that keeps food from the stomach from going back up the esophagus. Finally, simple space considerations exert force on the lower stomach, pushing contents up. All these factors contribute to increased heartburn.

Heartburn is treatable in pregnancy. Tums is generally considered the first choice medication. It is made out of calcium carbonate. This can not only help relieve heartburn but it also provides calcium supplementation in pregnancy. Be careful not to use more than the recommended dose or it can lead to kidney stones. Pepcid, Zantac, and Tagamet are all safe in pregnancy and are the second choice if Tums is not effective. Personally, when I have bad heart burn, I take Tums and Pepcid together. The Tums works quickly but doesn’t last long, the Pepcid takes a while to work but lasts a long time. Taking them together can provide rapid relief that lasts a long time.

14 weeks marks the start of the second trimester. This is the part of pregnancy when most people feel their best. The nausea, vomiting, and fatigue are gone and the baby is not yet so big as to be uncomfortable. Take advantage of the second trimester to get things done and have some fun. The third trimester can be difficult for some women as the baby starts to take up a lot of space.
