Is this an infection? Is this discharge normal?

Raven

I have been having this discharge for the past week and a half. I'm on the pill but I admittedly take it at different times every day. I have had unprotected sex numerous times this month. Sorry if this is tmi but I'm curious what could be going on? I have cramps on my left side once in a while and my breasts are tender and I'm having terrible mood swings. Someone have any idea what it is?
