in early pregnancy can using a urine sample from later in the day affect the "weeks " measurement?

In the morning your HCG levels are the most concentrated, however if it's a well known company like Clearblue, which invests heavily in their research and their product, it doesn't matter. Your HCG levels double every other day so when the test gives you an estimate of about how many weeks you are from your last period, given the range of the test (1-2wks, etc.) and a very general range of your HCG levels, the simple answer is no. Keep in mind this estimate based on how much HCG is in your urine, not if it's there, which is result of your "pregnant" or "not pregnant" result.

I had a faint line one morning with this test- got quant hcg the same day, and it was only 5.7. I also got a light line the day before a quant hcg of 11.

Honestly, I'm not sure. I was required to take these while I was pregnant to increase my levels. I assume less than 30 days because I had to go back every both to get tested and the following month my levels had improved. I took these during my entire pregnancy and they were great. No problems

If tested immediately,fresh urine is okay to use for both OPKs and HPTs. If 'not' tested immediately, urine may be stored at room temperature (59-86 F or 15-30 C) or 8 hours refrigerated at 36─46 F (2─8C) for up to 3 days.

I always use them right after. I collect my urine in a disposable cup and use the test strips right away. It always works for me. Hope this helps!

I started with 1/8 teaspoon dissolved in water. You need to get pH test strips to measure your first morning urine pH. You want to raise urine pH to greater than 6.00. Your individual dosage will differ from those of other people. Do your research.

My stretch marks are from my pregnancy and I didn't start using this product until about 7 weeks after having my baby. I honestly feel like I've noticed a difference in the week that I've been using it! However, I'm sure it depends on the type of skin it is being applied to and how deep the stretch marks are. I've noticed a difference on my lighter marks so far.

You are looking for your LH surge so you can test anytime. Urine is most concentrated in the morning, when you first wake up, but testing later is not a problem.

From what I understand, these tests are NOT very accurate and I wouldn't get them again. But, the same thing happened to me last month when I had a chemical pregnancy. I would try a different test in another day.

It was almost a year ago when you asked this question but I just saw this. The peak (3 bars) are due to a surge in luteinizing hormone (LH). LH first surges 4-6 hours after we wake up but as the monitor asks for the first morning pee it might miss it completely it some cases. If the doctor says all is well with the two of you, then try setting the test window for the second morning urine (between 10am and 2pm) for one cycle and see if she gets a peak. I hope this helps.

I believe this "theory" is based on the idea that you'll miss your LH surge for that day, by testing urine in the morning (which would have collected overnight). However, an LH surge can happen at any time, so you could miss it for the day no matter what time you're testing (you would, however, detect it in the next test). The only drawback to testing in the morning is that if you test, for example, at 6am on day 10, you're really only testing 6 hours from day 10 and 18 hours from day 9. You may want to keep this in mind when determining your testing window. Also, it should be noted that the directions do NOT state a specific window to test in, merely that you should test at the same time every day.

Absolutely! The "can detect as early as 6 days before your missed period" are just for people who like to know that much sooner. From experience, I have done it both ways, and it works. When it was done BEFORE my missed period, the positive line shows up faint, and they always recommend to follow up with another test about a week later anyways to be sure.

It doesn't matter when you take it, as this test is just for "fun". The reason they say it's not to be taken prior to 6 weeks is because that is the point at which the developing baby is either becomes a boy, or remains a girl. (All developing unborn babies prior to that are always girls, as the process that makes a fetus a boy or girl occurs about then. Therefore, it is impossible to know prior to that. This was probably the only scientific knowledge used in creating this test.)

I am not a doctor but in the past it has mean that there is HCG in the urine and a possible viable pregnancy is detected. Line should get darker as the HCG builds up in the urine. You can keep testing to see if line gets darker and follow up with doctors test. If line gets fainter, it could mean that the pregnancy was not viable

No, but it's better if it is concentrated. If you drink a lot of fluids through the day, the urine is usually not concentrated. That is why they recommend morning urine, which is approximately 8 hours after your last drink. My wife used to test twice a day and once the hcg level was above 50, it used to show up positive all the time with any urine, day or night.

Yes it can tell you the date of the babe due and how many weeks are you .As long as you have the date of LMP( 1st day of last menstural period)
