Hi,
Thanks for the query.
If you tracked the ovulation by kit, there is possibility of
pregnancy if you had
unprotected intercourse around that time.
But if you are thinking of ovulation just according to dates, that may or may not occurred.
Because after undergoing D&C, the time of recurrence of ovulation can differ from person to person.
If the pregnancy is there, the spotting you had could be
implantation bleeding.
In the absence of pregnancy the spotting could be due to causes like, hormonal imbalance, post ovulatory spotting etc.
Urine pregnancy test kit may not detect early pregnancy sometimes.

So better to wait till your expected date of periods.
If you miss the periods, go for
blood test for pregnancy or wait for one more week and repeat urine test for pregnancy.
Better to start
folic acid supplementation from nowonwards.
