Uncomfortable!

I have felt so blessed this whole pregnancy (currently 27+3). I haven’t been sick, haven’t gained much weight, truly no complaints. Ever since Sunday, I feel like I’ve suddenly gotten hit by a truck. “Down there” is swollen and throbbing and I’m pretty sure there’s varicose veins. My feet hurt and I just don’t feel myself. It’s like I’m finally “feeling pregnant” this far in. Anyone else fee this way? I did have my shower on Saturday and was on my feet all day and bent over too much while opening gifts so I’m not sure if that’s what set my body over the edge or if I’m just hitting the 3rd trimester wall.
