Ladies question I first started feeling slight stretching on my abdominal I know that normal since I'm almost 8 month on Monday my baby moving downward well yesterday I felt the same but with a slight burning feeling where I think my cervix is (which means in the inside) it didn't last long when I started walking but today I woke up with that stretching feeling and burning cervix feeling and no matter how much I walk now it wont go away what can it be should I tell my doctor about this Friday when I go in?
