Indigestion and heartburn are common symptoms of pregnancy and unfortunately, they tend to get worse the further into the pregnancy you get. This is likely due to the fact that as the fetus grows, the space in the stomach gets smaller and smaller. In addition, mood swings are normal throughout pregnancy and even for several months after birth. However if you feel depressed for a stretch of time, it worth mentioning to your doctor or midwife. Pregnancy depression is common but if the feelings don't pass and stay for a prolonged time, you should seek help.
