Itch!!

Abigail
I'm due my period on the 24th and we've been trying to conceive for about six months. This month I've got really sore nipples and strangely incredibly itchy arm pits but no rash?! I'm hoping this is the month. I took a test on the 19th (6 days before my period) and it was negative. Has anyone else had these signs in early pregnancy? xx
