Pregnancy Test On Birth Control
Same as without IUD: A pregnancy test, when done correctly, at the right time, has about the same accuracy regardless of whether or not a woman is on a birth control method or not (such as an iud or birth control pills). Technically speaking, a positive pregnancy test may be more likely to be a false positive if a woman is on birth control, because the birth control makes it less likely for her to be truly pregnant. ...Read more

No missed period was on birth control pills went to the doctor had a positive pregnancy test. Why positive pregnancy test??
See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that.

It would be prudent to discuss the matter with your doctor. ...Read more
Might: Birth control pills generally work by keeping a constant level of hormone in the system to convince the body it is pregnant, and not ovulate. Skipping or missing an active hormone pill (not the dummy pills) could allow the hormone level to drop enough to allow ovulation. It probably doesn't happen often, but could. Using additional birth control would be a good idea. ...Read more
On birth control + withdraw method.. pregnancy test negative 3 days before period supposed to start.. what are chances I'm pregnant?
Too soon to know: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about 2-3 weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine. ...Read more
HCG & BCP: The pregnancy test measures HCG which is produced by an implanted embryo. The test only becomes positive about 12 days after ovulation. The hormones of the bcp do not mask a pregnancy, so if you are pregnant then the pg test will be positive. It is possible that if you do not have menses on the bcp (some women do not bleed) then you may not realize that you are pregnant or when to test. Good luck. ...Read moreSee 1 more doctor answer

Pill pregancy?: Taking the pill will not interfere with the results of a urine pregnancy test. If you missed your period, you should get a serum pregnancy test from your provider or Planned Parenthood, which is much more accurate. Remember not to let more than seven days elapse after taking the last active pill of the previous package. ...Read more
I'm on apri the birth control pill. I've taken many pregnancy tests it's been 42 days since sex. Can my birth control make the tests negative?
Yes, indirectly...: Birth control will "cause" a negative pregnancy test, which is a main purpose of birth control pills... they prevent pregnancy, thus causing a negative pregnancy test (because the woman is not pregnant). However, no contraceptive is perfect, so if a woman gets pregnant while on birth control pills, her preg. test will be just as POSITIVE regardless of whether she is on or off birth control pills. ...Read more
