Feel like I am ready to pop

Jessica • I am 28, married, we have a 6 yr old boy and currently pregnant with our daughter :)
I am 33 weeks pregnant with my second baby. I feel like I am ready to pop. I am so uncomfortable not matter how I lay or sit it just doesn't work for me anymore. I don't remember feeling like this when I was pregnant with my son six years ago. Does anyone else feel this way and of so what are you doing to make it better?
