I haven't been visiting this forum in a while, but I have learned a few things from last cycle that will let me chime in on a couple of questions. My dd still wakes up a few times at night and I never get close to 3 hrs before temping in the morning, but I'm still getting a thermal shift and sometimes my temps are so consistent they will be exactly the same for days at a time, just as they were before conceiving so it is worth trying even if you have interrupted sleep.
Also, I gave up the nightweaning about a week after my first pp ovulation last cycle, but even though we are nursing again at night, I O'd on cd 24 this month which is only a few days after my old normal, so I guess the difference was taking the vitex (or maybe it was just time?).
On sore nipples- I experienced very sore nipples a few days around when I o'd this cycle. Then, after the temp shift it went away. I guess it was the hormones, so maybe the sore nipples could also be from ovulation and not just pregnancy/AF.
I think we did a better job timing the bd, so I am looking forward to POAS this weekend. Right now I am 7 dpo and feeling good!
Congrats to all the BFP! and good luck to all of you.
