usually they are saying the whole pragnancy is 266 days from LMP,when is ur due date count back 266 days :)
A December baby would have you conceiving in March. I conceived in March of last year and my edd was 12/21/2010 and I had my dd on the 9th. You likely conceived between March 13th-21st.
If you put in your LMP in a conception calculator, it says your dude date would be November 13th. This is using February 6th as the first day of your last menstrual cycle. This is what it gave me:
First Day of Last Menstrual Period: February 6, 2011
Probable Date of Ovulation: February 20, 2011
Possible Dates of Conception: February 16 to February 24, 2011
Due Date: November 13, 2011 (40 weeks)
When exactly are you due?
And my due date is December 8
Is it still possible my ex could be although I had two normal periods?
i think based on ur inffo more likely the other guy is the father
