I wish there was! I’m right there with you (just at 31 weeks along instead of 19). The best thing I can suggest is to be sure you get up slowly. Roll out of bed if necessary instead of trying to sit right up. Some of what you are feeling could be round ligament pain. The best thing for round ligament pain is to sit down, relax a bit, and let it pass. Sometimes a warm (warm, not hot) bath can help too. Some of it is also because of the way your muscles are moving to make room for your expanding uterus. I hope you can get more comfortable soon. You’re almost halfway done. :)
