I need some experiences. I've had my "period" for 4 days. And yes I know it seems long for IB. But hey, it's happened to some!

It was never really RED. No clots. No cramps. Nothing. It would be heavier in the morning then damping to pretty much nothing but when I wiped. Didn't go through more than 1 pad a day. Also didn't fill the pad. Pretty much one little line down the middle. Blood was more strawberry coloured. So if people have had this and if it was IB, can I get experiences, how long after first bleed to test?
