It depends on how much and how long you have taken it. If you just take a couple for fun you should be clean in a few days, with urine test. If your addicted, and they do a hair analysis test it can take a month, or more.
If your 10 days late for your period you counld certainly take the pregnancy test now. most test will give a accurate reading even a couple of days after your missed period. if in fact the test came back positive, only ten day after the missed period you wouldn't be showing yet.
If you had a positive pregnancy test then had a heavy period a couple days later, you may have had a miscarriage. If this happens, you should consult a doctor.
most likely not. wait a couple days and take the test again then get a second opinion from a doctor
No.
Give it a couple of more days, then take a test. You were really asking for it.
just lay off it for a couple days before test.
If you fail a drug screening test whether or not you are allowed to take it again is up to the company's drug policy.
You can order test online and get your results without anything added to your permanent medical record. Most places seem to be discreet and can have your results within a couple days.
It can be a possible that you are taking the test too early. You should wait a couple of days and take another test. Also, there are some women who have very low HCG lvls in there urine, for the first couple of weeks, which causes the HCG in the urice to go undetected. An easy solution to this would be to get a pregnancy test via blood. Good Luck.
