1 week late, nausea, tiredness but a negative pregnancy test

[Flynnshine]

I may be asking a VERY obvious question here but having been out of the TTC and pregnancy loop for a fair few years I thought I would ask the knowledgeable ladies of Mumsnet!

My period is now one week late, my cycles range from 25-30 days and my periods are never on time (max 2-3 days early or late)
We did DTD around the time I was allegedly ovulating (going by my period tracker log) although it wasn't really in an optimum baby making position! (sorry for the extra details!)
I took a test last night as I am really nauseous and a lot more tired than normal but it was very clearly negative... could there be a chance that it could be wrong? It was a Superdrug own brand pink dye one.
Are there such things as false negatives?

You are more likely to get false negatives if testing early. But you're a week late. You probably just ovulated late which would make your period late by the same number of days. Totally normal.

Good luck.

Im in the exact same boat im late and never late, so went and brought a clearblue test from morrisons an hour ago and its negative. Been feeling nauseous for days now and constantly tired. Will wait another couple of days and if another negative will go to the doctors

Just be aware your doctor probably won't see you until you've missed three periods. Late ovulation and anovulatory cycles are common (even if they aren't for you personally). A period is never technically late - it's the ovulation day that can change, and things like stress and illness can affect it. If you haven't had a bleed you are either pregnant or, if not, having a cycle without ovulation or with delayed ovulation.

Well, I bought an expensive Clear Blue test that day, figured I'd wait for the morning to take it and AF appeared that night! I'm still feeling nauseous though so that must be something else. I hope this isn't going to be the norm from now on
