Just wondering, at what point in your pregnancy did you become pretty seriously uncomfortable for one reason or another? Did it come and go or just come to stay?

I'm 27 weeks today and I swear the baby has moved into a weird position for the last 2 days that is pushing on my bladder in the most uncomfortable way. Sigh. She did it a few times earlier but it never lasted this long. My doc said this is super normal and that it will come and go and really only get worse from here on out. And that is just sort of depressing because I have 13 weeks to go!

So anyways. Just wondering about other people's experiences! When did you get uncomfortable, and was it constant or did it come and go until a certain point?
