How accurate is Flo gestational age?

I have booked an early scan for 6+4 but I’m worried that the Flo app isn’t accurate and the scan will be too early

There’s plenty online calculators you can double check with online that takes it from the day of last period, pretty sure Pampers does this as well

If you have regular cycles and know your ovulation date then it's likely to be accurate. If you have anything outside the standard it's likely not accurate

As far as I’m aware flo isn’t one of the most accurate apps out there as I do think it bases its predictions of a textbook 28 day cycle. Do you know when you ovulated? I use the app Natural Cycles which predicts ovulation with basal body temperature and LH ovulation testing strips. If you know exactly when you ovulated it will be a bit easier to work out if it’s correct. Xx

Also, if I were you, I would probably book your scan for just over seven weeks because although you probably can see something at 6+4, you are probably better booking it a bit later just in case you are earlier than you thought to save yourself a bit of disappointment and worry x I booked mine for just over seven weeks and I saw the baby and the heartbeat xxx

On Flo I was nearly 8 weeks but at my scan I was only 6+1 because my cycle was so long. I’d go at least 2 weeks after your first positive test if not a bit extra. We didn’t see much but we at least got to see there was a heart beat x

yeah I’m the same! I ovulated on CD22 so a week later than average! This puts me back a week earlier than if I was to base it off my LMP

Thanks everyone. I think I’ll push it back as getting different answers from different calculators x

I had my early scan and it turns out I must have ovulated about 2weeks later than I thought and with calculating based on the first day of my last period it is dating me 1month ahead, I would say wait till the scan to know how far along you are for sure
