Home pregnancy tests work by detecting a specific hormone which is present in pregnancy. "Spotting" has nothing to do with it, and shouldn't interfere as long as implantation has taken place.
No it wont.
Blood test are good for women who do not have enough hcg in their urine to detect on a home urine pregnancy test. A blood test can detect pregnancy before a hpt can. Hopes this help
with an hpt 5 days before your missed period.... or get a hcg blood test by your doctor
yes but you should wait at least until your next period is due to take a hpt.
Yes.
Brown discharge could be implantation bleeding or early pregnancy spotting which are both common. If your period is late, take a test or go and get a blood test.
Most HPT are reliable about 5 days after your missed period was due. Some claim they they can be used earlier but usually the hCG level is not high enough to test positive before this and you will get a false negative.
Yes! Some women don't produce enough HCG hormone in early pregnancy for the HPT to detect. If you are 21 DPO and your BBT is still hight, I would suggest going to the doctor for a blood pregnancy test.
It depends on when you are supposed to have your period. I have heard that you can take the test up to 7 days defore your period.
Possibly, yes. Even when used properly, not every hpt is 100% reliable. The brown spotting could be due to a pregnancy implanting itself in the womb, and the colour of the spotting could mean that the weight of the pregnancy is putting slight pressure on the cervix, dislodging any old blood that is laying around up there. Please visit someone who specialises in this area and get yourself a definitive answer.
When you get pregnant your body produces a pregnancy hormone that the HPT picks up. That is how it knows your pregnant. In early pregnancy the hormone is not always strong enough to be detected, that is why they suggest you wait until you miss you period to take the HPT. That is not to say it won't detect it, every pregnancy is different. If you want to know before you miss your period you should go to a doctor.
No, a HPT is meant for single use only.
No, a period and a negative HPT (used at the appropriate time) indicates no pregnancy.
