13weeks and bad pains 🤕

Nina
Hi!! So im 13 weeks and for the past week or so, ive been have horrible back pain and siatica (i have a bad back and the siatica before pregnancy, now it seems its getting worse) my dr isnt to worried about it due to my history, but the physical therapy isnt really working, and i would love some at home remedies i can do when it gets super bad. Ive tried heating/ice pads, yoga positions. Also yesterday i started getting wierd almost bump feelings in my tummy and pelvic area, sometimes painful, sometimes not, anyone know what those could be?? anything tips, tricks, tibits of info you ladies have would be wonderful!! Thank you!Â
