Lower backache starting yesterday at 6dpo while I was just sitting around playing cards against humanity with my gf’s. Came and went like in waves on the left side of my lower back. Today at 7dpo it’s been my whole lower back but more towards the left side still in waves from nothing to intense. This is very normal for me the first two days on my period during my heaviest flow. But never a week out from my period. Not sure if this means anything or I’m just looking to far into it. Hoping it’s are rainbow baby and would be amazing to tell the kids they are getting a new sibling for an Easter present!
