Signs of labor??

Laura

So ive noticed my lower back has been having a dull ache pain that wont go away an my legs are also cramping like the pain wont go away. I took tylenol extra strength for pain but that didnt really help the pain...

I am 29 weeks & 5 days.... anyone else feel the same & what helps you? Or could this be early signs of labor??? Hopefully i can see my ob doc tmrw
