Nighttime heartburn and back pain

So far this pregnant I’ve avoided getting any heartburn. I’ve gotten back pain on and off throughout. And then a couple weeks ago i started getting really uncomfortable when I sleep and have to maneuver pillows around weird. The past 2 nights now, after I’m already asleep, I’m getting such bad heartburn and back pain to where I’m crying. I can’t lay down because it makes me feel like I’m going to puke from how bad the pain is and the heartburn just sitting there. Last night I had to sleep propped up. I cannot do 10 weeks of this. This either needs to get under control or baby needs to come in like 7 weeks. I’m miserable and so over being pregnant. 😭😭😭😭
