When can you take a pregnancy test if you are on the birth control pill?

Answrer

The right time to take a pregnancy test depends on different factors, for example the type of technique ans the sample to use. If the technique is very sensitive it will be able to detect small fracctions of progesterone (pregancy hormon)present in the sample in a short time from the fecundation time. The sample has an important play as well. Urine has lower level of progesterone than serum. Hence it is more likely to have a positive result on serum in shorter time than in urine. To avoid false negatives results (negative tests because the level of hormon is not detectable yet, but the woman is already pregant) it is recommended to do the pregnancy test 2 weeks after the date the period supposed to come.

Answer

Any day after the expected missed period. If you do it before, it may be negative although in reality you are pregnant. The hormone levels are just not high enough to show.

Answer

It's recommended to use morning urine and not drink too much liquid before you go to sleep. Again, if you do it during the day or drink a lot of fluids it may dilute the hormone concentration.

Answer

You can take a pregnancy test four days before your missed period. Some tests work better than others. Use the one that stresses early pregnancy detection.
