Ovulation excision means that after a woman's egg is released, except for the safe period on the day and the next day, it is not safe for the next few days. This is because, in the days after the egg is released, a woman's body is waiting for sperm to enter, which can lead to pregnancy. Therefore, women need to be especially careful to avoid pregnancy during ovulation.

To avoid getting pregnant during ovulation, women should follow these tips:

1. Avoid sexual activity during risk periods.

2. Use condoms or oral contraceptive pills to prevent pregnancy.

3. Avoid taking emergency contraceptive pills within hours after sexual intercourse.

4. Have regular physical examinations to ensure you are in good health.

5. If you are worried that you may be pregnant, you should take timely measures.

In summary, women need to be particularly careful during ovulatory excision to avoid pregnancy. If a woman is concerned that she may be pregnant, she should take prompt measures.
