3.5 weeks for DD and 5 weeks for DS as i kept getting negatives with internet cheapies.

An old friend was 11 weeks with her son and 8 weeks with her daughter.

My SIL didn't know with her first until she went into labour at 38 weeks.

A woman who gave me first aid when i fainted at a bistro a week later found out she was 7 months pregnant, she honestly didnt look it she was quite slim.
