S.C.
It can take a few months for things to get back to normal. Have you had your blood tested after your d&c? I had to have mine checked until my hcg levels were back at 0. I think it took me almost 2 months to get my period. Then it took another 2 for it to get back to a schedule. I wouldn't be too concerned about it unless you don't have a period for two months or think you may be pregnant.
