Light period!!! Lasting 2 days!!!?

Hi everyone, so forever my periods have always been 5 days with 2.5 of heavy bleeding and the first and last day of spotting but this month I fort I was gonna come on my period on Wednesday , also my period was 2 days late. I had pink spotting at 8am on Wednesday, usually when this happens I come on within the hour or 3 hours max.

So now its 1pm I'm having heavy cramps which only lasted for 40 mins so I thought okay gonna start now, had pink spitting for that whole day but I wore a pad during the night as fort it would get heavy maybe and it did during the night, woke up pad was filled but with brown blood.

So now we are on "day 2" I call it "day 2" as the first day was spotting so I would really call it day 1 but anyways everytime I went to the toilet, there will be just a spot on the pad but blood would come out in the urine and this would happen for few hours til there was hardly anything comming out in urine and just tiny bit when wiping.

Long story short were now on day 3 and having really dark discharge on pad and only spec of blood when wiping and then by 10pm lastnight period finished then woke up today started getting more blood which was a spec of blood then it stopped and nothing for the past 3 hours.

I find so bizarre as I usually have heavy periods and I only had what I would call medium flow!

Sorry 4 the long essay but anyone who has experienced anything like that and could offer any advice, would be helpful thank you!!!
