progesterone causes a lot of symptoms similar to pregnancy hun - unfortunately it's a PITA cos it's hard to tell one way or the other!! given that the sore nipples have happened late in the tww though, is a good sign
I don't know if it's PG symptoms or not, but I've had the same thing (extremely sore nipples and heightened emotions) over the past week or so, and I've been on progesterone/estradiol pessaries as well. My IUI was on the 31st October, I started on the pessaries a week later and I've also been having progesterone injections.
I think they recommend you don't do a HPT as it's possible it could have an invalid result. Let me know how your blood test goes though, mine's not until Monday.
