back pain lower right side kidney

20 weeks pregnant with back pain on the right side only. Should I go to the hospital?
He had kidney stones about 3 years ago. I am now 20 weeks pregnant and having the same symptoms as before. Low back pain right side only. It hurts worse when I'm active. I'm very scared, is another stone or maybe a urinary tract infection. I immediately go to ER?
Considering its history – I was going to have it checked out
