So my period was two days late this month, but then AF came late Wednesday evening. It was a medium flow/heavy flow all until like Thursday evening. When I get home from work around 9pm I realized I only had light bleeding. No big deal. So I wear pads at night when I go to sleep. I woke up at 4am to pee, no blood. So I changed my pad again. I woke up this morning.. no blood. My period only lasted a day & that's not normal for me. I usually go the whole 4 days! I'm so confused.
