My period came 3 days early. And it only lasted for two days the first day heavy and heavy cramps. Second day nearly anything on my pad. Is this normal. My period is usually 3-4 days and on time. I should have started my period today but it’s basically over. Anyone know if this is normal? Just a freak thing or could that have been implantation bleeding? Not that I planned it but I guess it’s always a possibility when you don’t use protection 🤷🏻‍♀️
