So I'm either having implantation bleed or just spotting (which I have never done before.) Would you test positive now on a hpt even though the egg is just now implanting? Ovia says I should've gotten af yesturday glow say Wednesday but I just found out this cycle after opk testing for the first time I ovulate late which moved af start date back on glow but not Ovia. Ovia is always right. I just don't know have I missed my period, can u even test positive if the egg is implanting now, or just wait a few more days? Ladies your thoughts?
