when did i conceive?

Hi i'm due on Friday th 13 november. and i can't work out when i conceived !!!

I am 5weeks and 1day pregant I went on friday to the doctor I was 4weeks and 6days then. She said my due date is feb 14th from friday the 12th she said you count back 4weeks and thats what she did she said I concieved on the 15th of may wich I think is weird cuz I hade started my period the 10th the following 11th and 12th where bad and 13th and 14th I wasnt hardly doing anything at all and I hade messed around on those days and got pregant the day after. counting myself from may 10th I counted up to 4weeks and 6days and she counted back 4weeks and it was the 15th. soooo

If you can think when your first day was that will help you out alote. But since you know how fare you are count back 14teen weeks backwards and where you end is where you concieved:). I dont know how right my doc is I havnt been to the obgyn yet.

ok, i just found out about my pregnancy. i missed my cycle in june but it came early july which is not normal. my cylcle always start at the end of each month. according to the dr. i am 13 weeks...thats crazy. my husband is in the military and left at the end of may and came back at the endof june. no intecourse until later july due to family being around. i have to be further, i think i got preg in may. but, if i am 13wks as they say. when did i concieve? no ultrasound yet...

My due date is July 8th 2010 when did I conceive

the first day of period was sept 9th, i had sex with one guy on sept 18th, and had sex with another guy on sept 24th, my due date is june 16th! IS their any way to determine the father of my baby. I have two children already, im so scared the baby is not by the guy i want it to be with
