Four days after you ovulate? Or four days after your period is due?

Any pregnancy test could show a false negative if it's taken at the wrong time of your cycle. However a quantitative blood test -- one that will give you a number, not just a yes or no answer like a qualitative blood test -- is generally accurate.

To learn more about your cycles, you can check out the book Taking Charge of Your Fertility -- it will help you understand when you're most likely to get pregnant and also when a pregnancy test would be most accurate.

So, your period only lasted two days and you had lots of blood clots and as a result you might be wondering what is wrong. For many females, their monthly period lasts between 3 and 7 days, with the flow usually light at the beginning, increasing after a day or two and then tapering off. It is also not uncommon to have some blood clots. If this experience is unusual for you, it might be worth seeking advice from your doctor who would be best fit to put your mind at rest.

For Blood & saliva, there should not be a problem. This only last about 2-3 days, however the urine is something else. You won't be able to pass on your own for that.

The heart of a feotus starts functioning at 18 days [when the mother is only four days late for her first menstrual period], and by 21 days it is pumping, through a closed circulatory system, blood whose type is different from that of the mother.
