Details in description.. normal to feel pain on one general side at 8w?

If I go off of LMP I should be 8w+5 due to my area and doctors office I couldn’t get an appointment to confirm earlier my appointment is this Tuesday.. I’ve been feeling pressure and pain in my uterus going on both sides for the past 1-2 weeks. It goes back and forth, doesnt last long and not very painful but I can still feel the pulling and stretching feeling. Today all day and last night it has only been on my right side. It’s about two inches below my belly button and to the right. Please tell me what you think I’m so nervous for my apt Tuesday ...
