Hi so I’ve never ever had a period lasting more than 6 days. I did have sex my last fertile window but never got a positive on a test. Only faint lines So I decided to get depo. Well for the pst 3-4 days I’ve been haveing brown discharge....very light. What is this?!? Am I pregnant is this just a period? PLEASE HELP?!?

UPDATE: 2days later the brow discharge has stopped and now my discharge is pink! I’m nauseous and haveing horrible stomach cramps....is this because of the depo or is there a possibility I’m preg. Hey
