Period shorter after copper iud removal?

So with my copper iud I had periods that were like 5-8 days long, usually 8 days. I got it removed the beginning of January and I had no period till 2/26 (unless the slight bleeding after was a period) that lasted till today. It has been 4 years that I have had it in, so I don’t remember what a non iud period is like...is 3 days normal? Did anyone have shorter periods after copper iud removal that turned to longer ones? I am not complaining I am just confused and wondering if it’s going to come back in full force in a couple hours!
