Is there still a chance

Got back a bfn on Monday the day AF was due. She isnt ever late if anything early by a day or two from what glow tells me. I also always spot a day or two b4.. usually between 28-30 days lasting 5 days.. however got a procedure done in Dec to flush my tubes and remove a cyst.. ever since 28 days like clock work.. Im now two days late.. pms syptoms are usually lower back pain and being a bitch.. now for the last 4 days my nipples are sore, im dead tired, hungry, thirsty and a little cramping off and on for 3 days very unnoticeable unless im lying still.. no spotting, no back pain.. oh and I am super wet tmi.. for like 3 days now constantly.. do u think i still have a chance. Im scared to test and get another bfn
