TMI PICTURES

OKAY, can anyone help me I have irregular cycles , so idk when I’m ovulating. I don’t track it . However I’ve been off BC (Depo) for 3 months now . So I’m thinking maybe just maybe it’s a period then again I’m not sure . I’m curious if this could be period or IB . The strange thing is the spotting started two days before My normal periods usually started in the past . I have experienced breast increase and some cramping and sinus issues when the spotting started. It’s been going on for 4 days now I know it says IB can only last two days but every woman is different .

The spotting has been rusty brown , hasn’t changed to constant red flow !

Just some kind advice
