Pink Discharge??

I am about 10 DPO I think and I was going to the bathroom before bed tonight. When I wiped I had pink discharge? What is this is it just AF coming?? I need some encouragement please. I was thinking this was my month. I've never had pink discharge before my period!! My boobs feel weird I have been having tingling and the past 3 days back pain and bloating have been pretty bad....and talk about mood swings omg I have been a mad woman I'm pretty sure my co workers and husband are scared of me snapping at any moment!! Please help!!!
