Detailed Answer:

Thanks for writing to us. Followings are my comment:

1) Condom has failure rate around 15 to 27%. However, it depends on your ovulation time and condition of the condom after sex.

2) Late period may be due to hormonal imbalance and excessive mental stress. I suggest you to undergo one home pregnancy test to clear your doubt. It will be best thing to release extra stress.

3) On NEGATIVE test, you may require progesterone pill for 3- 5 days to induce period. In that case, you should consult with your doctor for prescription.

4) Take healthy balanced diet, avoid stress by regular meditation, keep bowel habit regular and maintain genital hygiene properly.

Hope, it helps for your information. Kindly, close the discussion if you don't have any other query.

Wish your good health and practice safe sex in future.
