So for the past few weeks I've been feeling on/off sick, light headed, night sweats and just not myself. Got what I thought was vvvf positive (see pic) day before period was due. Started to have a very lighter than normal bleed the day I was due on and it was pink / salmon colour, the day after it turned bright red and a little mucusy but still very light. This is unusual for me as I have really heavy periods, I've also been having cramps and backache(which I don't normally have)I've tested while having this bleed and having neg tests.
Any advice?
