dont really need to worry at this early stage.
sometime the egg is not relases at mid-cycle. that means the ordinally calculation cannot be apply to you.
for me.. I am a regular 30day cycle. but my EDD was adjust at the very begining (around 6wk after my LMP).. for 10 days later (fr 3 apr by calculation to 13 apr by dr... but 20apr by scan!!!) and still.. my bb is 1 wk behind in all these months.. but dr. said, if it's always 1 wk behind, that's no problem becuase the growth rate is ok. But if the growth rate suddenly slow down.. then that will be a problem.
thanks ar ... luckily, i can eat more now, so i hope the baby can grow faster and healthier lar. ..
i will see the doctor before chinese new year... i hope i will have good news to share ...
