Is it even possible I can be pregnant?

I've been TTC for nearly 2 years now & my AF is usually pretty regular, out by the odd couple days that's it. However I'm now on CD61...
On CD38-41 I had brown spotting on and off. Thought it was start of AF but it wasn't. The thought it might be implantation but it can't be as I'm still testing BFN with no sign of AF.
On Monday I started feeling nauseous & sick, especially after tea. My mouth would be watery and metallic tasting. My partner bought me tests to try on the Tuesday- these were Sainsburys own so after googling them I saw that they give false positives. Took one at night & one the next morning. Both BFP.
Bought clearblue combo & took the normal one last night BFN & digital this morning BFN.
(I've got pink dye tests on the way to double check)
Am I being stupid here, I'm CD61 is there even a chance I could be pregnant?
Are my levels too low to pick up on. I'm really not sure. I have spoken to the doctor but because I was due fertility help & it was cancelled because covid there is nothing they can do until the fertility ward is back open in my local hosp!

I'd say wait for the FRER, they are the most sensitive and will give you a clear answer. It's quite a long delay in AF, but never say never!

I would say the most likely thing is that you're not pregnant at the moment, and are probably going through a cycle with annovulation. It sounds like the spotting came when you should have had a proper period before. Do check with the frer to be sure though, and best of luck, it's always possible
