Indigestion!

Is anyone else suffering with indigestion? I feel fine when I wake up and as soon as I eat it's like my guts forget what to do and the food just sits in my stomach. It gets worse as the day goes on and is usually accompanied by heart burn! It's pretty miserable :( by about 7pm it's so bad I just go to bed because I know I'll feel better in the morning.  I've swapped vitamins in case it's pregnacare because I have read they can cause heartburn. Would love to hear some remedies! X
