It's not just lower backache, it feels a bit higher up also, just like a pre menstrual symptom. It's on and off but I get it on most days? Does this sound normal?!
Good Luck and Congratulations x
I had lower backpain on and off for a few days after ET with ICSI....and got a positive result, so yes, it is normal.
Is it a lower back pain? They say a lower back pain could be an early sign of pregnancy.
