I've spent so much money on tests and I'm so sick of seeing that one sad line!!

I have PCOS so I'm not always regular. I had three regular periods in a row feb-april and then skipped May completely. I had what could have been a positive OPK at the beginning of June but it was only as dark as the line, certainly not darker, and then I didn't take another.

On Saturday I thought AF had arrived but it was just pink discharge (which I normally get on the first day) for a few hours and then it disappeared. Nothing since. I tested on Sunday and BFN. I've been super bloated and gassy the last few days (but I have been on holiday so might be overindulgence) and today I feel a little nauseous, but not sure if it's in my head!! Should I test again or trust the test I did on Sunday?

I just don't know 😔😔

Side note, we've been trying since Jan but not really strictly, just seeing what happens. If AF turns up this month we're going in all guns blazing!
