date of conception -- confused! May baby :)

on january 2nd I had an ultrasound where I measured exactly at 19 weeks. does this mean I conceived 17 weeks ago (from that date)?

my first ultrasound gave me a due date of may 25th.. using calculators online it tells me my conception date would be around the 2nd or 3rd of September. does this seem correct? I am almost positive the date of conception was on the 4th of September, does that seem about right??

sorry if these are stupid questions, I just need some positive reassurance! I thought maybe some other May mommies might know when they concieved- possibly around the time I did. I know dating counts from LMP but I have not had a period in many months!

Im due the 16th and according to MY calculations, I got preggers around August 13....

www.baby2see.com is a great website to check your conception date. It also explains how they get due dates, and what month you are in based on your weeks.

August 31-September 8 based on an average 28 day cycle.

I'm due 2 days after you, and they think that my conception date was between September 6th and 14th. I personally think it was closer to the 14th, but I don't think there's a way to figure out the exact date, I just know we weren't having sex but every few days, so just go with your gut feeling I guess. You know when you were having sex, not a conception date calculator or the doctor unless you tell them.

Quoting kittty:“ on january 2nd I had an ultrasound where I measured exactly at 19 weeks. does this mean I conceived 17 ... [snip!] ... when they concieved- possibly around the time I did. I know dating counts from LMP but I have not had a period in many months!”

im due may 2nd my conception date says august 10th. thats what everyone has told me and im pretty sure thats what it was

ultrasounds don't give the exact date just an approximate... how many mommies really have babies on their due dates?? my doctor said that my due date was may 21st at first... but said i was 22 weeks (at the time) but if i were really due on the 21st i would really be 21 weeks n 3 days... so its jus an estimate... not exactly... the baby comes out wen they're ready but the date helps u estimate... my friend had her baby 7 weeks early and another one had the baby 2 weeks later... so therefor its a guesstimate...

also my doctor said i'm measuring a week ahead of most females who are also 26 weeks so instead of measurin at 26 i'm measuring 27... and honestly i'm not even that big!!! i see a lot of females on here that are huge (not in a bad way) n i still look normal just a lil preggo but doctor said everything is healthy n she said that i'm just eating right so after i have the baby i'll go right back to normal cause all the weight gain will be baby n nothing else   so everything n everyone is different!

Oddly enough...I'm pretty positive that i got pregnant on September 4th as well...lol....I'm due May 27th. At eleven weeks my ultrsound said that I was exactly on schedule for my due date and then when I had my next ultrsound on Jan. 7th it said I'm measuring a week larger....and then at my next appt. the doctor still insisted that I'm measuring bigger...I GUESS I'M HAVIN' A BIG BABY!!!

Thank you SO much, ladies!! The date of conception is very important to me because of an issue with the father. An ex boyfriend is trying to say the baby is his, when it is not. I know I had not been with him for months- and know who I HAD been with around the time of conception. However he chooses to dispute this, and I think with a solid time frame of conception he will let go and realize the baby is not his   <333
