Yeah, I would go in. It could be a sign of labor.
Call your doctor back pains can also be a sign on early labor depending on how often or if they are continuous spasms so I would call the doctor and see if they want you to come in for a checkup and make sure you and your little one are doing ok and maybe they can ease the pain a little for you
Im 35 weeks ,I'll be 36 weeks Monday
How far along are you? I miscarried and a symptom the doctor told me to look for was back pains (bad pains) or shoulder pains. And two days before my miscarriage I had a fever and shoulder and back pains. I was only 8 weeks though. If it continues or gets worse you might want to call your doctor.
