**************************
***IMPORTANT NOTE***
**************************
This app calculates exactly 280 days (40 weeks) from LMP to EDC, and accordingly for any date in between. Please note that the paper/plastic wheels used by obstetricians or ultrasound technicians are inherently inaccurate. Different pregnancy wheels may vary by as much as 3 or 4 days. Please keep this in mind when comparing the values obtained here to those given in clinics/hospitals.
