Patient's question:
I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried about it affecting fertility, and I'm also extremely sensitive to cold and coldness. Can you please tell me if taking birth control pills still works if the fertilized egg hasn't yet implanted?Doctor's answer:
The situation you mentioned refers to taking emergency contraception within 72 hours afterward, which has an effectiveness rate of 98%. Because, as you described, if the fertilized egg implants, emergency contraception contains high levels of progesterone, which can reduce the movement of the fallopian tubes and also inhibit the proliferation of the endometrium. This makes it unfavorable for the fertilized egg to implant.
