I had a D&C April of 08 it took 45 days for me to get my first cycle. I've always been 28 day cycle. After the first cycle they were anywhere from 30-33 days for the next 6 months before they got back to 28 day cycle.
After mc cycles can take a while to adjust,mine used to be 27-28 days,then went to 33-34 after my losses.most are never the same agin,wait few more days and test again,or see your doctor.
i understand completly how you feel.. i had a d&c on july 22 and just stopped bleeding 3 days ago. If your concerned then you need to go to talk to your doctor. I'm sure everything is fine. Sometime it just takes sometime for everything to get back to being regulated
