Period after D&C

Emma

So, I had a D&C on October 25th. I got my first period on November 16th. I still haven’t got my second period and today is day 31 of my cycle. I took a pregnancy test on Friday but it came out negative. Still i’m praying I might be pregnant. Has anyone had D&C and then got their period all messed up. I used to be regular before my MC. But now i’m just very confused!! Please girls, tell me your stories so I don’t feel all alone here
