4 days late and pain in breasts

Kristen • 24,married and trying for my first,after a chemical pregnancy July 2015.

Hello

Today I'm 4 days late

Took a test and was bfn :(

I started having some pains in my breasts yesterday and today it's more frequent. Last month I had a chemical pregnancy. Only symptoms I've noticed are the pains in my breasts and wanting to nap all day. I'm trying to not worry but I'm afraid I might have another chemical pregnancy.
