13dpo today but still BFN

Cassi

So I still haven't gotten a bfp or a vfl and I'm suppose to start my period in 1 or 2 days both apps I use are different. But I usually always have a lot of pms symptoms and so far haven't gotten any at all. Is this a good sign of pregnancy and it's just still too early for a test to pick it up?? I want my rainbow baby!
