Can i do a pregnancy tesy whils on my period as i dont have regular periods coz i have contaceptive implant?

Do pregnancy test: A pregnancy test on urine can always be done - just make sure it is not contaminated with blood, as this may interfere with the test results. And keep in mind that it takes up to a week for a pregnancy test to become positive; so use a condom or refrain from intercourse if the first test is negative and you need to do a second test to be sure you are not pregnant.

Sure: Of course you can, however it is likely to be negative.
