Thankyou! All pain n discomfort went away when I rolled over onto my back. Gonna stay up just a lil bit longer to make sure I am okay.
It doesn't sound like appendicitis, and there is always the possibility one of the kids has gotten into an uncomfortable position vis a vis some of your muscles or ligaments. I'd keep watching and waiting, and if it becomes problematic, phone your doctor's after-hours number and ask for advice.
