One whole month is a stretch. My docs were only off by a week with my LMP compared to my first.ultrasound. And even now he measures about three days ahead of what my weeks say. I don't know how it all works but like I said...a month seems like wide enough gap as far as gestation goes.
Google "conception calculator" @AHHHpenguins helped a friend and i not long ago with same dilemma! It gives you a couple options on how to figure who the dad could be. If you had sex with them both too close together however, it may call for dna testing. Good luck!
I found out I was pregnant at 18 weeks on February 7, and counting down from there had me freaking out for awhile. It didnt help when my ex-partner practically asked me if my son was really his :/ then he said he wanted a DNA test, which I should probably talk to him about..
First Day of Last Menstrual Period: October 4, 2012
Probable Date of Ovulation: October 18, 2012
Possible Dates of Conception: October 14 to October 22, 2012
Due Date: July 11, 2013 (40 weeks)
Does this help/ look close to right?
Sort of.. but I have irregular periods. Which adds to the complication :c
I totally understand :) But chances are good based off of your due date that your partner of two years is the father! Chin up hun! Life has a funny way of working itself out.. kinda like our funny bones, ironically & slightly painful but we laugh at it anyways :)
Regardless, im sure you will be a great mom ;)
