Home pregnancy tests (HPT) works by detecting a hormone called human chorionic gonadotropin (hCG.) When an egg is fertilized, it takes about 6 to 12 days to implant in the uterus, and then it begins to secrete hCG. It takes another day or two for enough hCG to build up and make its way into your urine. Generally speaking, the earliest you can expect a positive HPT is 8 days past ovulation ("DPO") and the latest would be about 16 DPO. It is possible to get a positive test earlier or later, but not as common.

In my experience, if you use a sensitive "early" test (anything that detects 25 mIU/mL of hCG or less) you can test around 10 to 12 days DPO and feel reasonably secure with your results (the later you test, the more secure you can feel in its accuracy.)

Note: some HPT's say "test 5 days before your period is due!". Please note they are assuming a textbook 28-day cycle, with ovulation on Day 14. "5 days before your period is due" thus really "translates" to 10 DPO.

How long after implantation bleeding will a positive test result?

I believe it may take 2-5 days in order to allow the pregnancy hormones to build up to a level where they can be detected by a home pregnancy test. Having said that, I took a pregnancy test within hours of having an implantation bleed with my son and it appeared positive within seconds!


What does bleeding time reflect?

Bleeding time reflects the integrity of the vascular system and platelet function in the body. It measures how long it takes for bleeding to stop after a standardized skin puncture, indicating the efficiency of platelet adhesion, aggregation, and the function of the blood vessels. Prolonged bleeding time may suggest platelet disorders, vascular abnormalities, or the effects of certain medications. However, it is not a comprehensive test for all clotting disorders.


I didnt get my period last month and i took 2 pregnancy test and both came out positive What are the chances that im not pregnant?

I'm not a doctor, but I sincerely have to say "not good". The fact that both pregnancy tests say positive, as long as you did them right, then your mathematical chances are all but 100%.


What does it mean if your 2 days late for your period?

It doesn't mean anything - unless you use fertility awareness method you cannot know for certain when your period is due, you can oly predict when your period is due based on past cycles. Anything up to a weeks variation from your average menstrual cycle length is considered totally normal. As long as there's no risk of pregnancy there's no reason to worry about a few days 'late' from when you were expecting your period - if there is a risk of pregnancy then take a pregnancy test to put your mind at ease.


What does it mean when you come on your period twice in one month?

It means just that - you came on your period twice in one month - it's no more complicated than that. If this was your period, and not your period plus some other vaginal bleeding caused by something else, then it is normal to bleed twice in one month occasionally. The average menstrual cycle is 28 days and as most months have more than 28 days if your cycle is this long or shorter you will see yourself bleeding twice in some months.

Implantation bleeding typically occurs 7-14 days after conception, not immediately after intercourse. This light spotting may appear around the time of your expected period and is usually shorter in duration than a normal menstrual period. If you experience bleeding and suspect it may be implantation bleeding, it's best to take a pregnancy test to confirm.
