Scared to be excited.....

My husband and I have been trying to get pregnant since November.....

I was supposed to start on Tuesday, my nipples have been KILLING ME for the last 6 days....still no period..... the night before last I squeezed my nipple and some clear stuff came out....which made me almost jump for joy cause that's exactly what happened when I was pregnant with my daughter...

BUT I did a test yesterday morning and it was negative so I'm scared to be excited.....

Thoughts???
