I'm trying to remember, what happened with the timing of your bd? Was it after O? I ended up with a weird attempt this month...had 3 low temps in a row and EWCM, so we dtd, and next morning had a temp rise, but then for some ODD reason, my temp dipped back down this morning and I still had a +opk and lots more EWCM, so we DTD again to be sure...I'm not holding much hope in my attempt either, and it seems strange things happen with everyone's cycles when trying to sway! Here's the link to my chart...

I'm sure I'll be feeling just like you if I get a bfp this month :(
