Thank you :)

Dear Madam,

Your narration could not clarify when did you have your menses, whether you missed it and on which day the cycle you had sexual intercourse. Also cannot figure out whether you are still on Cerazette, which is a birth control pill. In that case the chances of pregnancy are very remote.

To guide you further on the urine pregnancy test: Usual urine pregnancy tests are more reliable 8-10 days after missing the period, before which they may give false negative results. However, beta hCG tests are more specific and sensitive and can give reliable results even within 2-3 days of missed period. You may try this test to clear the dilemma in your mind if you have missed your period.

If you have not missed the period, please do not panic. Wait for your periods. If you miss the period, then only follow the guidelines about the pregnancy tests given above.

I hope this helps you.
