Ok so I re-tested last night, very strong negative line but the positive line was still there, but faintrr than last week's, today and last night I started feeling nauseous again, I know I can't be pregnant as we have only dtd once and we used protection and nothing went inside me, could this be my body preparing for my af? I remember after my first Mc i felt quite rotten befote it but I got my af soon after x
