I am the same way! 27 weeks tomorrow and it killed me for weeks! Definitely ypur tale bone! Idk if you ait at work but i brought a pillow to work and sit on it daily and it really helps! I also put extra padding underneath me while sleeping
It's your tailbone. It started for me at 20 weeks. It's now broken and still hurtS and my son is 1 and a half. You can get a pillow with that area cut out that helps a lot. Stay off it or on cushions as much as possible it will help. No hard surfaces.
Most definitely your tail bone its normal ive had it most of my pregnancy its excruciating pain i feel you. When the baby becomes heavyer its putting pressure on your tail bone and lower back bones. If your on your feet alot its worse. I always found it hurts more when i lay straight on my back. If its not that it could be a possible cyst as well thats common for people to get in that exact area. If you want to make sure ask your doctor your best bet.
May be hemorrhoids if not, pressure from your uterus... I'm 27 weeks and experience pressure in my bum crack lol I don't have hems
