i think you should go to the doctors and check out 1st why your peeing green ? and then check to see if your pregnant ...
Hi , i worked in nutrition for many years and i have never heard of vitamins interfering with a test. multivitamins ..would make your urine bright yellow, as its supposed too , cause thats showing its extracting from your body the way it was designed too,and almost all multis have b complex and D-3 or D2 in it. Docs also reccomend woman to take prenatals before they TTC so its obvious you will be on them at the time you pee on a stick... a good prenatal dosent have anything that will block a pregnancy hormone . as it come to the amino acid L-Phenylalne, and the her Valerian , i also never heard of it interfering with the hormone but their are many herbs that arent good to take when pregnant so you will need to verify with your doc if its ok to take any herb or amino acid...but vitamins are fine.....any who i would wait till next week, and if you still havent had it, then take a blood test that will confirm it.
FYI, Vitamin D3 is great for woman TTC, pregnant or for post pregnancy... !!!!!
