Doctors will assign a supposed 'first day of last period' if a woman has irregular cycles, because medical counts of pregnancy use it as a start point. It's not a big deal, I just didn't want to throw off miya203 by what you said about early March. For a birth date of December 15, the calculator says:
First day of last menstrual period: March 10
Probable date of ovulation: March 24
Possible dates of conception: March 20 - 28
Due date: December 15 (40 weeks)
and if you were 2 days earlier than 40 weeks 39w5d), it would be
First day of last menstrual period: March 12
Probable date of ovulation: March 26
Possible dates of conception: March 22 - 30
Due date: December 17 (40 weeks)
If a doctor assigned you the first day of last period and gave you an estimated due date from an ultrasound (sonogram), if it was much later than 7 or 8 weeks pregnant, there will be a margin for error in the figure (+/- maybe 1 or 2 days if in your 7th or 8th week, +/- 7 days if you are in your 12th week, all the way to +/- 3 weeks by the time you are full term). It is quite possible that a doctor could have assigned March 5 as the first day of your last period, but it would be very surprising if anyone ever said that was your conception date. All medical counts of pregnancy begin on the first day of the lmp.
Like I said, this doesn't matter really (you didn't say you were worried about who is the daddy) except it matters to miya that the information she work from not have issues of suggested times being wrong.
My last cycle was in december of 2014 so the doctors couldn't do it that way. They figured from the sonogram that that's what I was
Hi, hailere, your numbers don't add up to March 5 for conception if you had your baby on 12/15 and were told you were 39w5d gestational age. You might want to check them again. Conception would be around March 22, and the first day of your last period around March 8 or so. Doctors count the "weeks pregnant" as beginning on the first day of your last period, not on the day of conception, so perhaps that is what the 39w5d and the March 5 refer to. But nothing about being 39w5d and having a baby on December 15 adds up to conception on March 5.
I got pregnant on March 5th and had my daughter on December 15th at 39w 5d. I'd say the guy in early march, but realistically it could be either. Best of luck!
Nevermind I looked it up on the website , I see what I have to do, thanks!
Does it give you the results at home? Or do you still have to send it in to get results ?
I believe Walgreen's does sell a home test.
Yes of course, I'm aware that that would be the way to find out but I didn't want it to go through the court way cus my boyfriends name would be tooken off the birth certificate, my boyfriend knows about the situation as well and didn't want a dna test cus he doesn't want a bad outcome, my baby girl looks like me so looks aren't a thing we can go by. Personally I want to know for sure but he doesn't ..Is there one in stores that I can do??
If you have two possible candidates for Dad and the baby has been born, it is an easy enough thing to do a DNA test.
Right , they took that from when I assumed my period was and also did a crown to rump length, I wasn't sure where to find it on the ultrasound paper I have, I heard that was accurate in pregnancy
Because in an earlier post where you asked this same question, you said the baby was due on December 11 according to an ultrasound in your ninth week. That suggests conception around March 20.
No after March 17 I was only having sex with my boyfriend! I only messed up one time and that was the day on March 2/3. Can you explain the reason why you think it's my boyfriends ?
When you took a week off after March 23, did you have sex with anyone else? If not, I would say your boyfriend is the dad.
:( , hey, can you explain why you think it was the guy in early March?
I'd say the guy in early march, but you should have them take a DNA test to be positive.
