I the answer to this will be if AF doesn't arrive but... it doesn't stop me being impatient!
According to my previous two cycles, AF should be due on Thursday. I did OPKs and I'm not sure whether I used them properly or not but I didn't even get a line at all until I got what looked like a positive last Monday, which would make me 7dpo now and only 10dpo on the day AF is due. Should I test on Thursday, or wait until after the weekend!
