Due date confusion

skstaylor · April 2015

So i must confess I'm a bit confused about my due date....the bump calculator tells me im due 11/28/15 but that woukd make me 6 weeks pregnant which seems too far along. My first prenatal visit was scheduled for 8 weeks on 4/29/15 butaccording to the bump that woukd be 10 weeks. Any thoughts? I thought i was a December due date but now may be November..? O well I will find out at our appt in a few weeks

Thanks!

Are you entering day of last period or day of conception into the calculator?

What was the first day of your last period? Or, if you were temping, when did you ovulate?

skstaylor · April 2015

First date of last period was 2/21/15 which is what i've been entering in. My cycles were never a perfect 28 days which may be contributing also. Did not use temperature bc this was first month of trying for us.

Remember that pregnancy calculation starts before you actually conceive.

What @embuzz247 said ... if your last period started 2/21, that would put you at about six weeks right now. Did your doc determine your 8 weeks based on you telling them your last period date, or did you just approximate to them how far along you thought you were? the bump calculator seems accurate to me. I used another site's calculator and based on your last period, it gave me the same - 11/28.

The doctors asked for the same date. Thanks ladies for the input...looks like baby will be coming a few weeks earlier than expected!

Maybe, maybe not. Normal pregnancy.length varies between 37 and 42 weeks!

My last period start date was 2/21 as well. I told my OB that I have 36 day average cycles and that I tested on 3/31 and got a BFN. She then adjusted it to approx 12/6.
I started temping mid cycle since it was our first month TTC so thats not reliable to trust my O date. So technically I am 5w3d but I feel like she over calculated. How can I be 5w3d when I had a BFN 8 days ago?
So I understand your confusion.

I have found the bump accurate in my situation. On Monday I was 10w 3d and had an ultrasound.. Baby measured at 10w 3d/4d (2 different angles for the measurements)... And that is going off of my LMP.
