20 weeks cramping

Im frustrated with the cramping idk if I should worry or not. I have had cramping for a couple weeks now, I mentioned it to my Dr at about 18 weeks and he said its normal just my uterus growing. Its mostly on my lower right pelvis area. Like period cramps not too painful but annoying enough Id take some

Midol if I could.

Idk maybe I should drink more water?

Should I be concerned? Its bothering me a lot today, I do have a toddler and have been doing some cleaning(vacuuming, dusting, laundry etc) my normal stuff.

I have my 20 week ultrasound on Wednesday and baby seems to be moving fine, I feel her on and off all day.
