Patient's question:
The last menstrual period was around September 14 (I don't remember the exact date), and the coital date was October 6 (this time is certain). The menstrual cycle is usually about 28-34 days. Now, it has been confirmed that I am pregnant, but I have already been taking 4-5 days of Paracetamol and Chlorpheniramine Capsules since October 17. On October 18, I started taking Xipichlor lozenges for 3 days (the instructions indicate that pregnant women should stop using them) and Biyuantongqiao Granules. My husband had a chest X-ray during a health check-up around September 15. Now, it has been confirmed that I am pregnant, and I had a child who is two years old before. Can I keep this child?Doctor's answer:
According to your description, I suggest you preserve this child. Generally speaking, from the fertilized egg to the 18th day, as well as the fusion of sperm and egg to form a fertilized egg and the beginning of implantation, until after implantation when development has already started but before it has fully grown, that is, within 33 days of the last menstrual period, almost no drugs have been observed to have any teratogenic effect, meaning no interference with multiple embryos. This is because the embryo and the mother are not yet connected at this time. However, from the third week to the third month after fertilization, that is, from 33 days to about 13 weeks of the last menstrual period, this period is the most sensitive for fetal teratogenicity, making it the most likely time for congenital deformities to occur. You can undergo a screening for deformities.
