Letrazole cd6-10

Megan

Last cycle I took letrazole cd5-9, I had a positive OPK on cycle day 13 and confirmed ovulation on cycle day 14. This cycle due to the holidays I couldn’t start letrazole until cd6. My doctor said it’s the last day in a cycle that I could take it. Today I am currently on cycle day 14 and no positive OPK yet. Will I ovulate later since I took the medication later? What is everyone’s experience taking letrozole cd6- 10?
