BFN 2 days b4 AF advice please

Hey guys! I took a test this morning since AF is due Saturday and my boobs are crazy sore! Negative 😩. Do we think I can trust this? I have had a ton of trouble sleeping and my doc gave me a sleep aid to have if I am not pregnant  during AF and up to ovulation unless we start BD before that. Thoughts on whether I should wait or not?
