When to call a doctor?

Ja

I'm 34+1 and I woke up this morning with pelvic pain. It's not excruciating however it does ache when I try to change positions or when I walk. It's also a little in the hip area as well. Don't know if this is normal but just wondering for any second or third time moms is this something to be concerned about? I've pretty much carried "low" my entire pregnancy . Should I go into the hospital? Thanks in advance .

(P.S I called l&d; already but she said she couldn't give me medical advice)
