Okay I'm using this other app to track my fertilie days and ovulation.it say I'm suppose to have a period tomorrow which is the 7 I had a lil bleeding today not really heavy at all.. but on the app it says I'm in luteal stage day 28 but when i counted the time between my last period until today it only 24 days apart and a normal period is supposed to be 28 days apart .. but now the blood is dried up I think so I don't know if it implantation bleeding or what helping so confused
