Help with dates

[Olive]

I've been using the period tracker app for a while now. It say that I'm due 14 Jan (only realised this morning I could change it) and my acu today worked out the same. She said that she thinks I'm 4+6, so 5 weeks tomorrow technically, although not really when you think about it

Can anyone help me figure out how the app and my acu got this?

My cycles have varied and average is 33 days (i think)
First day of last period 10th April

(from this I get online that 20th Jan is due date).

Last cycle was 38 days and before that 29 days.
I'm sure OV on phone was cd20 but know I got a positive day 19.

I just don't get it!

Thanks to anyone that can help!

My friend had her last AF on 9th April, due 13th Jan if that helps I know some of the sites differ though x

Hmm, well i get 15th Jan just by literally counting 40 weeks / 280 days from the 30th April

Thanks girls. Need to try get it on my ticker but don't know how :-/ xxx

They must be counting from Sunday to Saturday = 14th, but it you count Sunday to Sunday = 15th.

I can get a ticker to say the 15th Jan by keeping the cycle length on 28 and putting last period as 10th April

Oh, i can get 14th jan (if you prefer) by taking cycle length to 27 days.
