Hi Everyone! Gotta dumb question for ya. I know they say there are no dumb questions, but... A mom I am working with casually asked me if I could tell her from her LMP and EDC dates when she conceived. She was embarrassed to ask her OB/GYN. The literature I have found doesn't indicate the calculations AND, having just moved, my "Pregnancy Wheel" is stuffed in a box somewhere. Can anyone let me know. Her LMP was 7/10/97 and her EDC is 4/16/97. I would appreciate the calculation but ,it would great to have her date of conception til I find that darn "wheel". Many thanks. Lucy, RN, BSN
