hi,

Thanks for the query.

clomid will help in ovulation induction,
if you had unprotected intercourse around the time of ovulation after taking clomid then the chances of pregnancy are there,
some urine pregnancy test kits are less sensitive and may not detect early pregnancy,
so you better go for blood test for pregnancy which will find out the possibility.
if comes negative better to consult gynecologist once to get examined for detecting the cause of delayed periods.

Hope I have answered your query. I will be available to answer your follow up queries. If you are satisfied with all my answer, please rate the answer after closing the discussion.
Take care.
