TMI. Help! Gas and indigestion!

I am 3 weeks and 5 days pregnant, I tested positive at 3 weeks 2 days. And basically since a few days after I ovulated even before a positive test, I have been soooo gassy and had such bad indigestion. I have these disgusting sulfur burps that are just killing me. When I lay down at night it gets worse. I have to get up every few hours to burp or I'm in pain. Tums are not really helping, GasX isn't really helping, though, I take both every night. What can I do? I have a feeling this is going to be my life the next 10 weeks. Please help.
