My period is late...

Beth
My husband and I have TTC for 9 months. My period is 10 days late. I took a pregnancy test yesterday morning and was disappointed to see it was negative. 
But I feel like I really might be pregnant. I've noticed increased wetness this past week which is unusual and my breasts are not sore which always happens before I start my period.
Is it crazy to go get a blood test to find out for sure?!? I hate this not knowing part!
