17DPO no AF but BFN. Low belly cramps, swollen nipples, brown discharge

Na

I have had early pregnancy symptoms since 9DPO as frequent urination, extreme bloating, light cramps on and off, dizziness, vivid dreams, headaches, tiredness. I got a BFN at 16DPO. Now I am 17DPO and a little brown discharge happened when I wiped today. I am going to wait for 20DPO to test it again. Anyone have gotten a BFP after having similar symptoms?
