Back pain and side pain

April👩‍👧‍👧

I’m 26 wks and on my second pregnancy. Today my lower back has been aching SO bad😩😭😰. I also have just been so uncomfortable today, like my right side and hip hurt, the right side of my belly aches, and my lower back is just awful. Any tips on pain relief??? Has anyone tried a pregnancy belt? My Dr suggested it to me last visit, but I don’t where to get one. Please help, I don’t know how I’m going to make it to October 10th like this😫 I’m a teacher and I have to go back in August. I’m totally dreading it being so pregnant, AND I’m the head volleyball coach so I have a whole season to get through before this baby comes out. 🤦🏼‍♀️😰
