Sore erect nipples and itchy vag!

So... this is third cycle TTC & im in the TWW- AF due 31st May ! I have had very sore erect nipples for 3 days now and itchy vagina (sorry tmi) and was wondering if any other ladies had this before bfp? As never had this the last 2 times or is it just some good old Pre-menstral signs? Thanks ladies x
