Just had my period which seems to be sitting at a 31 day cycle so have decided to do opks this month. Have taken one on monday (cd 6) which was negative so thought it might be too early to use them. Yesterday (cycle day 8) I noticed ewcm so did an opk which came up +be so DTD.
Today did another opk and the line was faint. Ovia says my fertile window isn't for 5 days so I am abit confused - have I already ovulated ? And if I have will DTD yesterday be enough ?
