so my depo expired April 3rd, I have had no af or anything until yesterday there was brown in my underwear & when i wiped only that 1 time there was nothing after that. this morning there is some brown when i wipe, if i put a tampon in and take it out there will be brown on it. I have no idea if this is AF?? or brown discharge? i am so confused. i have been cramping & boobs have been sore. i thought maybe implantation??? i have been ttc & had unprotected sex 6/4, 6/5 & 6/9 he did finish in me. just any thoughts on what this might be? i got my hopes up yesterday thinking maybe AF. Any help is VERY appreciated.

the picture is what is there EVERY time i wipe. its brown & looks like the beginning of AF? i just dont know though.
