How long after sex can I detect pregnancy?

If you do not take protective measures during sexual intercourse, it is relatively easy to conceive successfully. However, even if you succeed, the pregnancy test will not show immediately. It still takes about a week to test whether you are pregnant. Therefore, you should pay special attention to your physical condition in the early stages of pregnancy to avoid miscarriage.

The fertilized egg stays in the fallopian tube for 3-5 days before implanting in the endometrium. Some are earlier, some are later, and some vary greatly. 3-4 days after fertilization, morula is formed, and blastocyst is formed 6-8 days later. Implantation begins 6-8 days after fertilization and is complete in 11-12 days.

After sperm enters the female vagina, it can survive for 2 to 3 days. If ovulation occurs during this period, conception will occur. The lifespan of an egg is also about 2-3 days, while it takes one day for sperm to travel from the vagina to the fallopian tube, and two days for the fertilized egg to implant. So the time it takes to conceive after sex should be 2+1=3 days.

Symptoms of early pregnancy

1. Amenorrhea: The first sign of pregnancy is amenorrhea. For women with regular menstruation, if they have sexual intercourse during this month and their menstruation is delayed by one week, they should suspect whether they are pregnant. Some women will not stop menstruating after becoming pregnant, but there will be changes, such as smaller flow and shorter duration.

2. Easy to get tired and sleepy: After pregnancy, women generally show symptoms of sleepiness, and are easily tired and have no energy to do anything.

3. Vomiting: When the pregnancy is more than 6 weeks, women are prone to vomiting, especially in the morning when they are on an empty stomach. Their sense of smell becomes extremely sensitive, and smelling disgusting odors may cause vomiting. Pregnant women do not need to worry, as this is a normal phenomenon.

4. Frequent urination: In the early stages of pregnancy, pregnant women will often want to go to the toilet but cannot urinate completely. Don’t worry, this is because the uterus is slowly growing and pressing on the bladder.

5. Breast pain: Women who have just become pregnant are likely to experience tingling, itching or swelling in their breasts. As the mammary glands grow larger, lump-like masses will develop on the breasts. This is an inevitable part of being a mother.

6. Increased vaginal discharge: Increased vaginal discharge is caused by a sharp increase in hormones and is a normal phenomenon.

7. Hunger: You will always feel very hungry and want to eat in the early stages of pregnancy. This is normal and there is no need to control your diet. However, make sure that the food you eat is light.
