that is your coccyx bone!! you can thank the hormone relaxin for relaxing everything down there and now all the pressure is being put in the little bone thats a few inches long at the tip of your spine!! i have it too and all pregnant woman will get it eventually!! Congrats, youre pregnant!! =) it hurts =) its normal though!!
I had this my last pregnancy...until I delivered and about 6-8 weeks after. I hate to say it but it actually got worse the further along that I got, I'm worreid about this happening again. My tailbone actually ended up popping out of place...it was horrid I had to wear this weird wrap after delivery.
Have you tried changing positions often? I lay on my side mostly on the couch to prevent tailbone aches! Good luck!
same here; never had tailbone issues so obviously it has to be from being pregnant but i just wanted to make sure .!
That's funny I've been having the same problem. Only when I sit for long periods of time or if I sit on a hard chair or bench. Never had tailbone issues before so I figure it must be something pregnancy related. Let me know if you figure it out!
