Periods after a loss

Hi all, just wondering if anyone has experienced this or if I should be concerned at all? In May I had a miscarriage at 10 weeks. Since then I have had 3 cycles, they all came right on time. the first one after the MC was 11 days long and very heavy, the second one was still somewhat heavy but only lasted 2.5 days, now I am on the 3rd one I spotted for 2 days, literally just a spot on Monday and a spot on Tuesday. Nothing since. My periods are usually super predictable 4-5 days right on time. Is this normal after MC, it’s now been 3 months.
