Hi Sazzy,
Congrats on the birth. You may not remember me from 2005-06 but we had met through geoexpat once, I believe. You were going to leave HK shortly perhaps for Singapore, I can't recall precisely now. Well, guess what? I am back in HK too with 20 month old toddler and hubby.
Regarding your question, I don't recall having abdominal cramps. I experienced severe discomfort for many weeks as I had an emergency C-section and the abdominal area is incapacitated from that but I don't recall cramping. It gets better, one week is too early for the physical aches and pains to be a distant memory.
