Also, I was just thinking implantation can occur from 6-12dpo then takes a few days for hcg to show so really it still could be early. I dont know what my LP is as I have only just started using OPK's so I am assuming as I ovulated later my AF will be a few days later this month too, I think I have my dates correct, we will see if AF shows early or late then I can work it out. Also I assumed that I ovulated the day after my LH surge so ovulation may of occurred a day later than I thought, I could be 9dpo. I am having mild AF cramps at the mo, not due until Xmas eve I think so I am hoping this is a good sign. I love cramps!!!lol!! xx
