Okay so Ive calculated my conception sept 7 (could have been sept 6, but sticking w 7) Ovulation was sept 11th - II know I didnt concieve at ovulation, because we didnt do the deed during ovulation .I tested positive Sept 28, and this line was a bit dark ( it was dark half way up and then light half way up lol) I only get a positive test after exactly three weeks. (Was that way for both kids found out with my first at 3w3d, and Luke 3w. ) So my nurse told me I am 7 weeks preg. My due date is 5/31 at 38 weeks. But I counted and Im only 5 weeks. So how did she get 7? I mean the dd is correct at 38 weeks, but why did she say I was 7 weeks? If I concieved on the 7th up until now, Im only 5. Or are they counting two weeks before that? My last period was aug 24th. Im trying to figure out why she said I was 7... I know the ultrasound will confirm just trying to figure it out.
Since they count from the day of your last menstrual period and assume you conceived a textbook 14 days after that date, and I know the date I conceived, I just subtracted 14 days from that and gave THAT date to the doctor as the date of my last menstrual period. This way the EDD they gave me is forced to be based on my conception date!
I know that they calculate that way because it's a good ballpark until they can get sonogram measurements, but I've been tracking my cycles so I already came to the dr knowing my due date and exactly how far along I am, sooooooo they need to know too lol
Okay, now I'm confused. Why is your doctor giving you a due date that's only for 38 weeks? I know I'll be delivering early with the repeat c-section, but my doctor's EDD (which I contend is wrong) is based on a full 40 weeks.
What was the first day of your last period? Your EDD is 40 weeks from that date. HOWEVER...what day did you ovulate on? (My EDD is June 10 based on my LMP but I say June 8 because I O'd 2 days early). Even though you BD'd 4 days early, if you O'd on the 11th, your EDD would be June 4, based on ovulation, regardless of what you started your period.
I'm not a medical professional but pregnancy is my hobby. Have you ever read Taking Charge Of Your Fertility? it's a book by Toni Weschler, and I recommend every woman read it. It can show you how to get pregnant, how to avoid pregnancy,. and debunks all myths about the female body that, unfortunately, old school doctors keep telling us.
Basically if you KNOW when you O'd, 38 weeks after that day would be an accurate EDD. Keep in mind that only 5% of women deliver on their EDD though!
