Patient's question:
On the 18th of this month, when my period was about to stop, I had sexual intercourse with my boyfriend. The next day, my period stopped, and I felt some pain in my vagina. Two days later, I had another sexual encounter with my boyfriend. The next day, he bought and took a post-coital contraceptive pill. On the evening of the 24th, I noticed that my vagina was bleeding again, just like my period. I don’t know what’s going on? Could it be pregnancy? Or something else? I’m so scared!!Doctor's answer:
Okay, here is the translation, following your instructions:Normal, birth control pills can delay the next menstrual period due to their function of inhibiting and delaying ovulation, as well as their effect of inhibiting the uterine lining. It can also cause menstrual bleeding to occur earlier if taken temporarily, resulting in a temporary increase in hormone levels in the blood, followed by a drop and subsequent withdrawal bleeding.
The side effects of birth control pills may lead to endocrine disorders, menstrual irregularities, amenorrhea (absence of menstruation), infertility, or gastrointestinal discomfort, headaches, weight gain, nervousness, low mood, skin hyperpigmentation (age spots/sun spots), and acne, among others. Birth control pills should not be used more than three times within a year, and only once per month. We recommend you use other forms of contraception.
