Dates/how many weeks - Premom App

[BCLL]

Is anyone able to help please? I am pregnant and I've been using the Premom app to track my ovulation, I ovulated between the 1-3rd of March and had my BFP on 15th March (this is when the app told me to test) my app has now changed to pregnancy mode and it's saying I'm 6 weeks pregnant. When I input the info of first day of my last period 7th of February and 40 day cycle into the NHS app it's telling me 4 weeks?

I have a 40 day cycle and I know most things are worked out on a 28 day cycle, can come help please?

I need to contact the hospital for them to scan me at 6 weeks due to a chemical pregnancy I had at the end of last year.

Thank you for reading!

If you ovulated on 2nd March then today you would be 4w2d. 😊

And, congratulations!

The 40 day cycle will be confusing the PreMom app so go with what the NHS one says which accounts for your longer follicular phase.

Perfect thank you so much!

@duedateworry does that mean I would be 6 weeks on the 30th March?

I’d say perhaps a couple of days later. If you want to go for an early scan I’d aim for the 7th week if you can wait that long, so w/c 8th April 😊

Thanks so much this has been super helpful!
