Freaking out

Hannah
So about 4 weeks ago I started spotting for about two days and then I had a period. About two weeks after that, I started having sore breasts. No nipple color change, no swelling. 
Well I was supposed to get my period today but I didn't. I've taken multiple pregnancy tests this month because I am so concerned about what is going on with my body. My boyfriend and I have been TTC so we really have been very "active". Multiple times a day, everyday. 
But yet we've had 7 negative pregnancy tests. I'm guessing it would be best to wait a few days and even a week to see if my period starts before testing again? Right?
