I feel the same way. I am around 25-26 weeks depending on which due date you are using. I feel like my bump keeps bumping into things and I'm feeling like I'm waddling already. I keep getting these weird pressures down there. Our u/s last week showed that he was breach so I'm assuming his butt is pushing on my cervix.
My DH was complaining last night after dinner about how full he was and had to unbutton his pants. He jokingly said "you have no idea how crappy this feels." I looked at him and was like "umm try feeling like that every second of every day!"
It was much easier last time b/c I was just dealing with pregnancy exhaustion but this time I have pregnancy exhaustion, FT working mom exhaustion and a 2 1/2 year old exhaustion. We have a long 3-4 months ahead of us!
