So this month I've not got a clue when i'm due to O, my cycle has been 33 days for the past 4 months last month I started spotting at 27 and AF made an appearance on day 30 after thinking I had defo done it that month. So this month I'm not so sure, for the past 4 days i've had very thin milky cm not sure whether this means i'm due to O, i am O or I already have.... Im not due my AF until around 29th aug depending on how my cycle works this month. Thats working it on an average of 30 days
