22 dpo and no af but tons of milky white discharge...can it be a bfp?

before BD today my husband said that he could not find my cervix, and I have been having tons of milky white discharge. I have been feeling a bit...well unusual lately my sinus's are REALLY bad. I've been expiercing some odd back pain, heavy swollen (with a nasty big blue vain which I don't usually have) and just and over all tiredness. I know this may be tmi but I am wondering if I was like over reacting about a possible bfp.
