Patient's question:
I am almost 20 years old today, and my husband and I are not willing to use condoms. We are afraid of the side effects of taking medication. I want to get an IUD, but I'm worried about potential problems. I have a fungal vaginal infection.Doctor's answer:
If the menstrual cycle is relatively regular, the safe period method of contraception can be used. Most women have a menstrual cycle of 28-30 days. It is expected that ovulation will occur fourteen days before the next menstrual period. The days outside the ovulation day and the following 4-5 days are considered the safe period. However, the ovulation process can be delayed or advanced by various factors, and extra ovulation may also occur. Therefore, the safe period method is not very reliable, with a failure rate of 20%.
