Hi, just wondering how are people certain of the exact day of ovulation? What do you’s use to track it? All I’ve ever used is OPK’s now I had a positive OPK today which I know means I SHOULD ovulate within the following 12-48 hours. But how do yous know when it happens exactly? I’m just trying to find out which cycle day I will be on when I do ovulate so want to know what to check for.
TIA x
