Thank you all for your answers and kind well-wishes.
I can't wait for tomorrow to get my results at last. Wish the stupid doctors would open on a Sunday! lol I just want to kind of sleep all day to make the day go quicker or something... so I don't have to actively wait. It's driving me crazy.
I am now on CD30, AF should be here in a week if I'm not pregnant. I think I either ovulated (or implanted?) on Friday 3rd. I had mild-period-like cramps and spotting. Thought it was probably ovulation at the time, but if I am pregnant most likely implantation? It's been 9 days since then. If it was ovulation, I probably am not pregnant as it takes 7-10 days for the fertilised egg to reach the uterus and implant. If it was implantation bleeding surely a pregnancy test should show positive by now (9 days later)?
I don't know. I'm beginning to go back to my original feeling that my body is playing some sort of cruel trick on me.
