You may want to look into a chiropractor if it gets bad enough. Babies cause our bodies to change extensively, and a chiropractor can put everything back where it should be, or at least get you through the pregnancy.

@stephsmith212, I definitely will try that

The same thing happened to me when I was 33 weeks, I used a heating pad and it healed me! Doctor said it was because the baby was breech and putting pressure on my tailbone but the heat got her to turn head down and I have zero back pain now, it's worth a try!
