Ok so I was due on Sat, although that was based on a 28 day cycle and mine are consistently under 26 days, usually around 24 if not shorter. No, we rather stupidly, had unprotected sex the end of last week, but only when it was past the point where I'd usually expect AF to show up iyswim, I'd been having cramps like AF was about to start. I did a test yesterday, just to rule out pregnancy and it was very definitely a negative. So what's going on? I have had flu this month, could that have delayed my period? If that's a possibility, could ovulation have been delayed also meaning we may still be at risk of me getting pregnant, or would a positive have shown up already? I had some spotting mid (normal) cycle which I thought was ovulation, although I don't usually get spotting. Gah.
I guess I'll just have to wait a bit and re-test if it doesn't show, I'm not good at waiting though 
I had a mind once, now I have small children.
