Currently TTC my second baby. With our first I just used my app to inform me when my ovulation date was but I’ve since found out that isn’t really reliable so started using OPKs. But now I’m a bit unsure as to how many DPO I actually am. Was using Clear Blue OPK. Got an empty circle on Monday morning, solid smiley Monday evening. I assumed this would mean I O’d Tuesday but from reading around it could even have been as late as Wednesday evening into Thursday? Is this accurate? I’d love that to be the case as still testing negative even though I thought I was 10DPO and thought I must be out this cycle. Any help is greatly appreciated!
