Most confusing month since ttc

Stephanie
4 days after my supposed AF. Now my boobs are so swollen and tender oh man are they tender. Basically a ton of BFN (maybe a line maybe not) on dye tests and I am forcing myself to wait till the weekend for a digital test. I am only 13 maybe 14 dpo at the most. Just trying to understand what's is going on I am so confused.
