Light period??

Tye
So this is my first period after starting the pill and normally my periods are 3 days with the 1st two days being the heavier days and the 3rd day light with the 4th day I get light spotting. Is it possible my bc is making my period even lighter?? My period started yesterday and it seemed like how all my other periods start, and I use tampons but there's not a lot of blood and I think there's too much blood to be considered spotting. (I spotted two days before coming on my period) has anyone had this happen? Is this actually my period??
