I was soppose to start my period July 24th and now it is aug 1st and still no period so that would make me 8 days late but last night I took a pregnancy test and it came out negative but I think it was flase negative because I drank a lot of tea before I took it. My friend call planned parenthood they told her that I should wait intell Saturday to take one. I always had a period every month and now I'm not having one and I'm not under stress at all I've been feeling queasy and going to the bathroom a lot and sleeping a lot... So I Need Help

I would do exactly what PP told you to do.

Are you trying to get pregnant? I note that this is NOT your first pregnancy scare - https://www.askmehelpdesk.com/search.php?searchid=11482390

No Not really trying to get pregnant but not using in protection but I don't know I still have no period so I don't know what to do yet

If you're not using protection, then you're trying to get pregnant.

You said that you took the pregnancy test in the evening. A pregnancy test is most accurate first thing in the morning, with first morning urine.

Try again on Saturday morning if you don't get your period.
