It is possible though not probable that you could ovulate on time after a D&C. On the other hand, it's possible that your body is gearing up to ovulate about now--I would often get cramps, sore breasts, and backaches around ovulation during my cycles or it could be signs of PMS and your period will come on soon. You could probably test now if you like or wait a week or so and test again if your period doesn't show (keeping in mind that your cycle may be wacky because of the D&C).

Symptoms can be really confusing and don't necessarily mean anything; they could be signs of ovulation, PMS, or early pregnancy. When I found out I was pregnant, all I had was a missed period accompanied by period-like cramping--so very little in the way of symptoms.
