Had a 1 day period then brown spotting the next day. how long should i wait to take a pregnancy test? was on depo for 6yrs and have had 3 periods now.

Tests are accurate: Home pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, STDs, or medications. A urine test gives a reliable result 3 weeks after sex (3 weeks after when conception might have been), 1 week after missing a period, or 1 week after starting a "weird" period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon.
