I ve been trying to conceive from last three months after I suffered from chemical preganncy miscarriage. My period is due on 4th Sep. On 2nd sep I could see brown discharge just few drops. On 3rd sep it got little heavier and bright red flow, approx half a pad. Again today on 4th sep it is lite with few drops of red flow. My usual period also lasts for three days and it comes on time every time. I am confused whether this is implantation bleeding or regular period.. please help
