I've been getting the nausea this cycle too. Started mid-LP last cycle (I felt pg for a couple of days, just like before my BFP last year, but tests were BFN and then AF arrived) and it has continued daily throughout this cycle. I just had a wave of it a few minutes ago (4 or 5dpo). It's driving me nuts...
Juniper, I'm about that many DPO too. How funny would it be if we were due on the same day again??? (Yep, we've decided to try a month earlier than planned )
