Itchy Nipples!?!?!?!

Heather
Would any of you ladies help me out. I am 1 day late on my period and my boobs hurt soooo bad and my nipples are super itchy! I think I might be pregnant but I took a test and it was neg. Have any of you guys had this happen to you and then start your period.? The last time my nips were itchy like this I was pregnant with my daughter. I would just like some opinions. I'm just freaking out lol.
