So last month I had a 24 day cycle. I came on 11 days after ovulation. This month I ovulated on day 18 and am now CD 27. I usually spot before my period and before last month I had a regular 28 day cycle. Would I class tomorrow (cycle day 28) as the day before my expected period or two weeks after ovualtion as the day of my expected period, which would make it this coming Saturday..

I'm so confused
