Am I pregnant? TMI

Mo
So my partner and I had sex 3 times while I was ovulating. We use withdrawl method. 
At 7 DPO I experienced light spotting in a brownish color that smelled horrible. I am now at 9 DPO and I was horribly moody, extremely tired this whole weekend, my sense of smell is through the roof and I was in pain all day. 
Am I imagining the symptoms? Are they due to my period? I've never spotted before which is why I was confused. 
Has anyone else experienced this and what was the outcome? Thank you all!
