Pain in lower uterus/abdomen and sharp shooting pains in my inner thigh/groin at 39 weeks pregnant

For the last hour every time I stand or sit in a weird position I get a sharp shooting pain in my left upper thigh right up by my groin, and I also have some pain in my lower uterus and a ton of pelvic pressure. Could it be a labor sign? My dr office is closed so my option could be to go into l&d and get checked or wait it out.
