A week late....

R
So I am a week late, no positive test. I've been having what I would call normal period cramps though. This morning when I went pee, a chunk of pink tinged discharge came out, but no Aunt Flo. I leave for a trip on Thursday, should I wait it out or try and get an appt at my obgyn before I leave? 
I've been having more painful periods for about the last 6 months, had a very early miscarriage (the day after testing positive, so I'm not sure I can even call it a miscarriage) that sparked those in September. Went to the dr in Oct. did an ultrasound because my right side (around the ovary) was constantly hurting. Even when my period comes it's always the right side cramping, never the left. The ultrasound showed my right ovary was twice as large as my left, but still considered in the "normal" parameters. 
I just can't adult today, and need someone to brain for me haha. But seriously, I just need so advice/input/a shaman.....
