I'm 11w6d and I started having back pain yesterday it's across my lower back and somewhat hard to explain the pain. It definitely feels stiff somewhat crampy. I am trying to stay positive but after having two missed miscarriages it's hard. Does anyone else have type of back pain across lower back? I have had it for the 2nd time today . I am thankfully going to doctor this week and pray I get the reassurance I am looking for.
