A big congratulations! The conception of your baby has taken place. During the first trimester, you will adjust to being pregnant, to your new symptoms and feelings. Many women feel miserable during these first three months, while others seem to glow with health. Symptoms of the first phase can be managed by learning how to deal with them.
In the second trimester of your pregnancy, you are in the middle of your pregnancy. During the first three weeks, morning sickness and fatigue should be fading. During the second trimester, your bump will grow and you will feel your baby moving. When should you schedule an appointment with your doctor during this stage? Find out what is normal during this stage.
A pregnant woman’s third trimester can be physically and emotionally challenging. It’s time to start making preparations for delivery, choose your birth partner (if you want someone to accompany you), and discuss your expectations with a doula or nurse. Prepare for your baby’s arrival by learning what to expect during the final stage of pregnancy.
If your doctor needs more information about your hCG levels, they may order a blood test. Low levels of hCG may be detected in your blood around 8 to 11 days after conception. hCG levels are highest towards the end of the first trimester, then gradually decline over the rest of your pregnancy.
Human chorionic gonadotropin (hCG) is known as the pregnancy hormone, as your body produces it in large amounts when you’re pregnant.
Although you can have low levels of hCG in your body at any time, the levels of this hormone tend to rise sharply early on in your pregnancy for two reasons:
About 10 days after conception, the fertilized egg attaches to the lining of your uterus and your body starts to make hCG. Over the next week or so, hCG levels will increase.
At about 4 weeks pregnant, the egg—now called an embryo—implants further into the uterus and begins to produce even more hCG, which triggers increased productions of other hormones like estrogen and progesterone.
Together, these hormones help build the lining of the uterus and send signals to the ovaries to stop releasing eggs, ultimately stopping your period
The week-by-week chart below will give you an idea of how your hCG levels may rise during the first trimester, and then dip slightly during the second trimester. Keep in mind that, if you want your hCG blood test results explained in more detail, your healthcare provider is the best person to ask.
| Pregnancy week | Range of hCG levels in milli-international units per milliliter (mIU/mL) |
|---|---|
| 3 weeks | 5 – 72 mIU/mL |
| 4 weeks | 10 – 708 mIU/mL |
| 5 weeks | 217 – 8,245 mIU/mL |
| 6 weeks | 152 – 32,177 mIU/mL |
| 7 weeks | 4,059 – 153,767 mIU/mL |
| 8 weeks | 31,366 – 149,094 mIU/mL |
| 9 weeks | 59,109 – 135,901 mIU/mL |
| 10 weeks | 44,186 – 170,409 mIU/mL |
| 12 weeks | 27,107 – 201,165 mIU/mL |
| 14 weeks | 24,302 – 93,646 mIU/mL |
| 15 weeks | 12,540 – 69,747 mIU/mL |
| 16 weeks | 8,904–55,332 mIU/mL |
| 16 – 29 weeks | 1,400 – 53,000 mIU/mL |
| 29 – 41 weeks | 940 – 60,000. mIU/mL |
The amount of hCG in your blood can give some information about your pregnancy and the health of your baby.
