Patient's question:
When do situations like vomiting, craving for sour things, and being able to eat occur?First follow-up question: My menstrual cycle is not regular. It has been 51 days since my last period, and I still haven’t gotten my period. Last month, my cycle was 48 days, and the month before that was 43 days. I don’t know what’s going on. Today, I took a pregnancy test, but it only showed one red line. Some people say that you can test 3 days after intercourse on the day of ovulation. My temperature was also elevated yesterday and today. Why is this happening?
Second follow-up question: Lately, I’ve been especially hungry and eat a lot but get hungry quickly. I don’t know if I’m pregnant. I’m really anxious and want to know as soon as possible…
Doctor's answer:
Hello, implantation usually occurs 6-8 days after cohabitation, with the earliest being 6 days. After implantation, blood HCG levels will rise. Pregnancy tests detect pregnancy based on urine, so it is absolutely impossible for it to be 2 days. It usually takes at least 7 days, and sometimes even more than 10 days. This is because if HCG levels do not increase significantly on the day or the day after implantation, or if the test paper is not sensitive enough, it may not show a positive result. However, blood HCG can definitely be detected 10 days after implantation.It should be noted that sperm can wait up to 72 hours after entering a woman's body to fertilize, while an egg can survive for up to 24 hours after ovulation. If you ovulate 72 hours after cohabitation, you need to subtract three days. Therefore, it is also normal to wait 12-14 days after cohabitation to test.
Advice: We recommend testing with first-morning urine for the most accurate results—that is, the first urine sample of the day before going to the bathroom or drinking anything. We suggest you buy tests from different brands.
