Is Clearblue Advanced for me?

Hi,

My fiance and I are getting married in August this year and aren't ready to have a baby yet. I am very interested in the Marquette method which utilises Mucus and Monitor. For the monitor, is Clearblue Advanced the one for me?

I have irregular and long cycles. Here are some I have recorded in a PeriodTracker app on my phone (last year):

Mar 4- 31 days
Feb 1- 35 days
Dec 28- 29 days
Nov 29- 29 days
Oct 31- 36 days
Sept 25- 59 days
July 28- 25 days
July 3- 45 days
May 19- 39 days
Apr 10- 30 days

Will I be able to use the data? If I would like to start from scratch if I start using the Clearblue-- would this be possible as well? Approx how many Clearblue test strips will I be needing to start recording from scratch?

I understand that Clearblue is mainly for those with cycle days of up to 40 days? Based on my records, I event went as high as 59 days in 2014 and one 57 days in 2013.

Any other information will be appreciated.

Thank you.

Ellie
