Aww I am sorry to hear about a/f, and I
hope charting makes things clearer for
you!
You can take temps orally or vaginally,
but decide to one and stick to it for the
whole cycle. Although most people do it
orally! (i didnt realize this untill I
looked it up either!! Lol) make sure you
take temp as soon as you wake up in the
morning before getting out of bed or doing
to much movement as this can effect your
result!!
Wishing you loads of luck for this month!
