so the last two days I have taken 4 test (2 per box) each other was either taken at night or in the morning.. it’s seems as thought my FMU test are always negative but the ones that I take at night all have very very faint positives. i bought another two this morning and it’s a bold negative however it was a cheap brand and i have been using clear blue / first response. Am i over thinking it? I mean the line is still there in the old test? I still feel extremely nauseous and weary everyday. my period still isn’t due till thursday. wWhat should I do? should I stop testing and expect AF?
