Do I need to fast for a blood test to check for pregnancy?

Pregnancy is a big event in a woman's life, so once you feel signs of pregnancy in your body, you should check whether you are pregnant in time. If you are pregnant, you should pay attention to your diet, go for prenatal check-ups and other necessary things for pregnant women. Some women have possible symptoms of pregnancy and need to prepare for a check-up to see if they are pregnant. Some women don't know whether they need to fast for a blood test to check for pregnancy. Is it necessary to fast for a blood test to check for pregnancy? Let’s take a look at it next.

1. Do I need to be on an empty stomach when taking a blood test to check for pregnancy?

Generally, blood tests to check whether you are pregnant do not require fasting. You can determine whether you are pregnant through blood tests about 7 to 10 days after having sex. Therefore, it is recommended that you go to the hospital for a blood test in time after having sex, without fasting. After the pregnancy is detected, it is recommended that you also have a B-ultrasound examination, one is to further confirm the pregnancy, and the other is to determine whether it is an intrauterine pregnancy.

2. Pregnancy symptoms

1. Amenorrhea: The most common symptom of pregnancy is amenorrhea, but pregnancy is not the only cause of amenorrhea. Therefore, not all amenorrhea can be regarded as pregnancy. For example, serious illness, surgery, shock, mental fatigue, tension, etc. can cause menstrual cycle disorders. Other women successfully conceive, but they may experience some vaginal bleeding during the first 6 months of pregnancy, and some may have a little bleeding every month throughout the pregnancy.

2. Fatigue: Fatigue is caused by increased progesterone levels in the body, and progesterone has a calming effect. In addition, the metabolism speeds up in early pregnancy, so you may feel very tired, and sometimes you can't control yourself and want to go to bed immediately.

3. Breast changes: In fact, breast tenderness may occur before menopause. The nipples become soft and sensitive, the color becomes darker, and the veins dilate and spread throughout the breasts.

4. Changes in taste: As hormone levels increase, the sense of taste may also change. For example, there may seem to be a metallic taste in the mouth, or some foods may taste different from before, or even the foods that you normally like may no longer be appealing to you.

5. Weird sense of smell: If you think that liking the smell of gasoline and shoe polish is weird, you can try your own reaction: smelling some smells that you once loved will suddenly become strong and disgusting and make you want to vomit, such as perfume, coffee and cooking smells.

6. Nausea and vomiting: This phenomenon is called "morning sickness" because most pregnant women feel nauseous and stuffy in the morning. Part of the reason for this is that your blood sugar drops when you're fasting, causing vomiting. Although this phenomenon is called "morning sickness," it can happen at any time.

7. Frequent urination: When the embryo is formed in the mother's body, the body will secrete a hormone called hcg. As the progesterone surges, the blood circulation in the pelvic area is accelerated, stimulating the bladder and anus, causing women to often need to go to the toilet.

3. Reminder

After pregnancy, have regular prenatal checkups, eat a balanced diet, and maintain a good attitude.
