Patient's question:
After sex, feeling unsafe and suspecting pregnancy, how many days after can a test kit detect it?7 days have passed since sex. Is medication still effective now?
Doctor's answer:
If calculated from fertilization, a regular pregnancy test is usually around 14 days, which is the kind that says pregnancy can be detected 7 days after conception. This is because it takes 3 days for the fertilized egg to reach the uterus, and then 4 days for implantation to occur after reaching the uterus. Adding these together gives 7 days. After implantation, hormonal changes in the body will begin. 7 days later, HCG levels will significantly increase. There are also more sensitive tests, such as David's test kit, which claims to detect pregnancy 3 days after conception, which is about 10 days after fertilization. It is said that some pregnancy pens can detect pregnancy on the very first day, though I haven't seen one. However, when you have intercourse, it may not be on the day of ovulation. Sperm can live for up to 3 days. If you add these 3 days, if the test result is negative, then you definitely haven't conceived.
