Mrs P - Thanks for that. I haven't yet noticed any signs, other than a bit of twingeing in the lower abdomen. Also (probably TMI) but I am a little constipated and I think my sense of smell is heightened, but I am probably just imagining it all .... No sore boobs at all yet, though on the last two IVF cycles I had swollen boobs and they were sore/tingly and they were both BFN.
