Pain in my right side, back kidney area

Je

For the past 4 days this pain Has been increasing in severity I initially dismissed it as round ligament pain but am concerned possibly an infection brewing thought thought thought you ladies have any advice or insight? Waiting on a call back from my doctor more than likely I'll go in to be checked out but thought I'd throw it to you gals. Thanks!! Im 38 weeks along...and have no other symptoms except being overall extremely uncomfortable. Ive increased my water, decreased activity levels as i can, and use heat to help with the pain, but still the pain its increased and constant.
