Sore breasts

Kayl

So my period is in 2 days and I took a pregnancy test at 5 days before my period which came up negative but I've been having sore breasts. I never have sore breasts when I'm about to get my period. The last time this happened I found out I was pregnant with my daughter who passed away at 16 weeks. I am kinda freaking out. Is it to early to test?
