I'm grateful for clubcard vouchers and any little extras but I've realised recently that when I shop at Tesco 2 or 3 days before my period, I get a till voucher for £1 off tampax. I initially thought it was a coincidence but it has happened for the last 3 cycles now. I got one the other day and it prompted me to think - oh shit yeah, I'm due on.
Like I say £1 off tampax is great, but AIBU to feel a bit weirded out by the fact that Tesco have a closer handle on my menstral cycle than I do?
