Carla - No.. my transfer was on Monday (day 3 embie) so I'm 8 days post transfer. Was yours a blastie though? I think my clinic allow extra generous (frustrating!) days before final BT.
BBs are only slightly sore, probably due to the hcg injections I do every 3 days.
I have moments of feeling a little strange/possibly nauseaus but I'm pretty sure it's in my head.
I thought i had a bit of spotting a few days ago but dont know for sure - that very lightbrown-tinged CM which is gone again now... but I've had that before with unsuccessful cycles.. i know my progesterone must be OK as I had a mid luteal with fine results and am on pessaries.. so who knows!

Hope your sore BBs are telling you something great!
