occurs when unprotected intercourse
happens around ovulation in an otherwise normal couple. Duphaston
is a progestogen and helps in endometrial strengthening and not in conception. Hence, you should wait for your next cycle and if you miss it, go for a pregnancy test 3-7 days later with a fresh early morning sample of urine. For an earlier and better confirmation, you may get a serum beta-hCG
test 10-14 days after ovulation. Hope your query is answered. Good luck.
