Weird periods after d&c????

What were everyone’s periods like after a d&c? My first two were completely normal. My last two have been super random bleeding throughout a 6 day time frame. Like I can spot one day, bleed the next, brown spot the next day and then bleed again and back to spotting. Like it’s so weird. My normal cycles are heavy bleeding the first few days with moderate/lighter bleeding until day 4/5 and brown spotting on day 6.

I was super concerned about how weird these last two cycles have been so my doctor is doing an HSG to check for scarring from the d&c just to put my mind at ease.

Did anyone have weird cycles after a d&c after having a few normal cycles first directly following the surgery? Does that make sense like normal and then weird? Just ready to get back to my normal predictable periods!
