Help!! I dont know how to calculate how far along I am?

Hey ladies - Im getting majorly confused!

All the different websites with calculators are telling me different things, giving me different dates...

My GP gave me the due date of 15th April (based on some little wheel calculator thing she had in her office).

My last AF was on 11th July (so 4 week this Sunday ago), I am certain that I O'd on either 21st or 22nd July (so almost exactly 2 weeks ago). I have pretty regular cycles of 25 days.

One website is telling me that I am flat out 4 weeks pg.
Another one (and my ticker) is telling me I'm 3 weeks 5 days pg.

A good friend of mine just found out she is pg and get the same due date as me 15th April but her GP told her she is 4 weeks along...

I'm so confused! There is a proper way to calculate how far along u are? Or is there a reliable website to use??

Congrats Kristy!!!!

Check out : Due Date Calculator – Calculate Your Estimated Due Date

Mind you, 4 weeks vs 3 weeks 5 days isn't all that different - you could split the 2 :) If you're really desperate, you can ask your health provider to send you for a dating scan ....

Congrats!!!

lol I know it seems so silly to be wondering about the difference of a few days! But like all the info I'm reading is separated into Week 3 and Week 4.
I still think that I am Week 3 so I dont want to be sent info on Week 4 yet! :rofl:

I like that calculator u sent me though! Its telling me Im 3 weeks and 6 days. I guess its going to be one of those things where 'your never going to know exactly' how far along you are?

I really just need to be patient...thats sssooo not going to help me over the next 9 months! lol

Don't worry about 2 days, it's only an estimate anyway - you're baby will very likely come at least a week or so later than that anyway, since you're a first-time mum.
It is hard to be patient, especially the first time! Hope all goes well for you.

The little wheel your GP used calculates the EDD based on "textbook" 28 day cycles with ovulation occurring on day 14. If your cycles are 25 days then you probably ovulate around day 11ish and your GP's estimate will be slightly out. You will get a more accurate date at your scan at 12 weeks (if you choose to have it). Babies rarely come on schedule though and in fact even though a pregnancy technically lasts 40 weeks you are considered "full term" at 38.

Sit back and enjoy the ride, your bub will be here soon. It comes around so fast....

some of the due date calculator's will let you go by your O date, it's more accurate.
Just tell your dr and the hossy that you know when you O'd, and go by that.
