Hi any one who can give me some advice please ? it says my ovulation days was the 22nd of August and the main day of ovulation was the 25th of August on my fertility app. My period started on the 14th to the 17th of August but the 17th was just light spotting. I have now started with period pain cramping sensation and bleeding red blood but I’m not due on my period till the 9th of September and I also have like period pain. I also took an ovulation last Thursday and it was positive. What could this be?
