Hi I am 7 weeks pregnant, I have had on and off back ache since I found out I was pregnant I put that down to things changing and expanding down there but I hadn't had much in the last week or so had my 6 week scan which was all normal which I'm relieved, but last night I had back ache again not severe just a dull ache across my lumber area most of the night does anyone else have this at 7 weeks is it normal? Or should I be worried that's it's come back again?
