The product "Clearblue Advanced Pregnancy Test" states clearly on the label, however, that it is not meant to be a test used to monitor for miscarriage. With this test, as with other pregnancy tests, the notes above pertain. If you are worried you may have miscarried, talk to your doctor.
A doctor will interpret the results as 1-2 meaning you are 3-4 weeks pregnant, 2-3 meaning you are 4-5 weeks pregnant and 3+ meaning you are more than 5 weeks pregnant.
If your period is regular and lasts 28 days, and if ovulation generally happens on day 14 of your cycle, then conception probably took place about two weeks after the LMP. For gestational age counting, these two weeks are added to a pregnancy as a simpler method than trying to track from ovulation or fertilization.
The sensitivity of Clearblue Easy Earliest Results was 25 mIU/mL, which indicated detection of 80% of pregnancies.
In week 4 of pregnancy, your body is beginning to form the placenta and amniotic sac. Symptoms like abdominal pressure and tender breasts may appear this week, and as the cluster of cells that will soon become your baby burrows into your uterine lining, you may also spot some implantation bleeding.
Early pregnancy symptoms (at 4 weeks)
- a missed period (often one of the first signs of pregnancy)
- a metallic taste in your mouth.
- sore breasts.
- nausea (also known as morning sickness, although it can strike at any time)
- tiredness.
- new likes and dislikes – anyone for blueberry muffins with pickle?
Standard hCG levels
| Pregnancy week | Standard hCG range |
|---|
| 3 weeks | 5–50 mIU/mL |
| 4 weeks | 5–426 mIU/mL |
| 5 weeks | 18–7,340 mIU/mL |
| 6 weeks | 1,080–56,500 mIU/mL |
Urine hCG concentrations reach 10 to 25 mIU/mL by 7 to10 days after conception. Urine pregnancy tests have a sensitivity of 90% to 97% and a specificity of 99% for pregnancy during the first week after a missed menstrual period.
High hCG levels in pregnancy
As with low levels, high levels of hCG do not necessarily indicate a problem with a pregnancy. Some women simply have higher levels. If a woman has high hCG levels, it could point to twins or triplets, though only a scan can confirm this.Typical hCG Results4 weeks: 5 - 426 mIU/ml. 5 weeks: 18 - 7,340 mIU/ml. 6 weeks: 1,080 - 56,500 mIU/ml. 7 - 8 weeks: 7, 650 - 229,000 mIU/ml.
Whereas some at-home digital pregnancy tests have a sensitivity of 20 mIU/mL (meaning there needs to be at least 20 mIU/mL of hCG in the urine), the Natalist test has a sensitivity level of 10 mIU/mL, making it more sensitive.
hCG Levels Chart
| Pregnancy week | Range of hCG levels in milli-international units per milliliter (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 |
The level of hCG in your body increases in the early stages of pregnancy. Clearblue Digital Early Detection can detect tiny amounts of this hormone in your urine (the sensitivity of this test is 25mIU/ml).
(For example, the Clearblue Early Detection Pregnancy Test claims more than 99 percent accuracy if you test the day of your expected period or one, two or three days before; 96 percent accuracy four days before; and 79 percent five days before.
According to Cole's research (PDF), Clearblue Easy and EPT are both less sensitive than First Response but more sensitive than other tests. These tests also detect hCG-h but not as well as First Response.
You at 4 weeks
Conception usually takes place about 2 weeks after your last period, around the time you release an egg (ovulate). In the first 4 weeks of pregnancy, you probably will not notice any symptoms.Your Week 2 Checklist
Engage in sexual activity as you approach mid-cycle, notice fertile cervical mucus, and feel an increase in your sex drive. Continue taking folic acid or prenatal vitamins. Try to keep sex about your connection rather than a means to an end.Early pregnancy symptoms
Most women don't feel anything until they've missed a period, but you may notice bloating, cramping, or spotting this week. Your breasts may also be more tender than usual and you may have a heightened sense of smell, one of the earliest pregnancy symptoms.You can recreate first-morning urine for a pregnancy test by not using the bathroom for at least 4 hours. Using an early pregnancy test at night is another option if you're further along in your pregnancy. Blood tests are more sensitive than urine tests and can be performed in your doctor's office.
You should wait to take a pregnancy test until the week after your missed period for the most accurate result. If you don't want to wait until you've missed your period, you should wait at least one to two weeks after you had sex. If you are pregnant, your body needs time to develop detectable levels of HCG.
Pregnancy TestsIt's too early to take a home pregnancy test in week 3. But, by the middle or later part of next week, you might be able to detect the pregnancy hormone hCG in your urine with a sensitive early test.
Ultrasound tests work well to find out how long you have been pregnant, especially if they are done before 20 weeks of pregnancy. Some doctors always do an ultrasound in early pregnancy. During an ultrasound test, a small device called a transducer is moved back and forth over your belly.
3. Calculate using a pregnancy test with weeks indicator. All pregnancy tests are designed to detect the pregnancy hormone human chorionic gonadotropin (hCG) in urine, but some pricier tests offer a “weeks indicator†that promises to tell how far along you are.
Yep, that's a week or two before you even get pregnant. We know it sounds totally weird, but it's more accurate for doctors to estimate a due date this way. So if you think you conceived about two weeks ago, you're probably at least four weeks pregnant—maybe even five.
At 5 weeks pregnant, you're now in month 2 of your pregnancy. This week, you can officially take a pregnancy test — your hCG hormone levels are high enough to show a positive result, and you may have early symptoms like fatigue and nausea.
Your weeks of pregnancy are dated from the first day of your last period. This means that in the first 2 weeks or so, you aren't actually pregnant – your body is preparing for ovulation (releasing an egg from one of your ovaries) as usual.
Early pregnancy symptoms (at 5 weeks)
- a metallic taste in your mouth.
- sore breasts.
- nausea (also known as 'morning sickness', though it can strike at any time)
- mood swings.
- new likes and dislikes – anyone for a slice of orange with pickle?
- a heightened sense of smell.
- needing to wee more frequently.
