I have no idea, sorry AJ. I didn't have any signs of implantation. No thermal shift, no cramps, no spotting. In fact the reason I thought I was pg, is coz I had NO symptoms! Usually I have sore BBs from just after O to AF, but I had nothing.

I think it's best to wait the 14 days after O, as it can take up to 10 days to implant, and then the hormone needs to increase enuf to be detected by the tests. I got a very faint line on day 14. Try and hold out till then if you can!!
