Heavier Periods After D&C??

M

My periods have been light for about 12 years, leaving only like a saltine cracker sized area of blood on a regular pad. I had a D&C January 10th and my 1st period after it (3 weeks after) was light and normal. I started my 2nd period yesterday and today it’s so heavy that my pad is 3/4 full! Has this happened to anyone else? I haven’t had one this heavy since high school and it’s really odd. 😖
