@Me&Smooches This time around I started just using my CM (that's how we got DD last time); then introduced OPK's after a year (I use First Response OPK's); now, another year & a half later, I'm temping as well because I have to (I'm on Serophene, which I believe has the same active ingredients as Clomid). I don't like temping as I find I'm obsessing about everything more, panicking when my temp dips after O, rather than calmly hoping it's a sticky cycle.
6DPO & my temp dropped below cover line today. It has happened each of the 3 cycles I've done BBT, so most probably not an implantation dip. I strongly suspect I'm out for this cycle. Had some hot flushes, but no other symptoms. B00bs aren't sore at all (my nipples have been very tender after O for the last few cycles). I really thought we got it this month... But most probably not.
