I was feeling so positive :(

I’m 13dpo and I thought I’d do a test this morning and I got a bfn. I’m not due on AF till tomorrow but I’m feeling so down by it all. I had such a good feeling this month and to see no line just hurts. I’ve been having headaches, sensitive nipples odd dull like cramps and backaches and nothing. I just feel like it will never happen 😥
