2 days before my period I started bleeding it’s a light flow bright red little to no cramps feels different from my normal period on day 3 of bleeding it stopped for a day then started again still bright red little blood flow the week before I had back pain that would come and go with cramps coming and going felt like throwing up but just the reflex of it I feel more tired than usual with constant peeing . I have no idea if it’s my period or not I started bleeding Sunday and Wednesday it stopped bleeding but come back now I’m not bleeding anymore

Can anyone help me out???
