it is better to avoid pregnancy
at least for 2 months after D&C, as meanwhile your endometrium will recover and your general condition also like hemoglobin
status etc will come to normal.
after D&C the time for recurrence of ovulation varies in women,
sometimes it may recur within 2 weeks sometimes it may take few months depending on how much endometrium removed and when HCG
levels completely decrease etc,
so if you want to conceive early trace your ovulation with kits and plan intercourse around that period but as I told better to wait for 2 months.
