Should I be concerned if I’ve gained a pound every day this week? Up 5 pounds from where I had been steadily maintaining for several weeks?

I’m 37 weeks and 3 days today, and I’m actually still about 5 pounds under my pre pregnancy weight. I lost about 20 in the first trimester being sick, but with a higher BMI to start doctor was not concerned. I’ve slowly gained some of it back since about week 20, but had been hovering about 10 pounds below pre pregnancy give or take a pound or two here or there. But everyday this week that I’ve gotten on the scale, I have gained another pound. Have not changed my diet or lifestyle or anything.

Partially worried because at a checkup yesterday, my blood pressure was slightly elevated from my normal (132/83) when I’m normally between 110-120/65-75 ish. I have had some swelling in my hands just this week, but not really in my face or feet.

Is this something to be concerned about? I’m not worried about the weight itself, just want to make sure it’s not a sign of a bigger issue with me or baby.
