Can weed cause a false pregnancy test?

actually seeing as though your a constant user of weed this can make you permanently infertile so its likley that you could have damaged your reproductive organs with drugs first you need to see a doctor and get your fertility tested then to find out if your pregnant take a pregnancy test 2-3 weeks after you had sex (any sooner and the results won’t be accurate) in the morning with your first pee is the best time and take it when your period is due alternatively, see a doctor for a blood test this will both let you find out quicker and give you more accurate results and if you are pregnant youll need to stop smoking weed because it can end up affecting the baby, giving it birth defects or giving it withdrawl symptoms when its born because its addicted to the drug or even killing it

well see I know I can get pregnant because I have a 8 year old and also a year ago I was pregnant as well. I am late by almost 2 weeks now. I have taken a couple different brands of home tests and all came back false.

then it would be best to talk to your doctor about it and see a doctor for a blood test which will both let you find out quicker and give you more accurate results than a pregnancy test

Weed doesn’t have anything to do with a woman’s fertility, but after repeated regular use it can lower a male’s sperm count.

The drugstore pregnancy test looks for a hormone in your urine, and that hormone is very weak at the beginning of a pregnancy, and that may be why it’s giving you a negative result (false isn’t the same as negative). If you really are pregnant, then you could say it gave you a false negative result.

The blood test from your doctor, as jaz says, will give you an accurate result.
