Period was 3 days late no bleeding at all & my period is right on time with this app. On the four day of my suppose to be period I start spotting and it’s lasted for 3 days so far and still going when I wipe sometimes there’s blood sometimes there is not. Not enough blood for a tampon and I no spot on my panties or anything. If I stick my finger up my vagina there is blood so I am not sure exactly what’s happening because this has never happened before. Any thoughts to what this might be?
