In the evening, my lower back feels slightly heavy and my uterus is quite sensitive. I also go to the bathroom very frequently, but only for small amounts. The baby moves around in my belly, even though it's not much, unlike before. There are also strange sensations either in my uterus or where the bladder is, like tapping and pressure. Could this be pre-labor? I really want to give birth already, I'm tired and I also want to meet my daughter soon).
