Late period after iud

Kelsey

So I got my iud out at the end of June.. I’ve had one period since then. It started the 26th of July. Before my iud I was on a 28 day cycle.. thinking I was going to start my period last Sunday but it’s still not here... took a test yesterday morning and it was negative. I guess my question is.. is it normal to have strange periods after 3 years of having an iud... should my period be this late?
