Is this my period?!

I had a miscarriage a little over 4 weeks ago. For the past 3 days I had a white discharge. Today I had some brown and pink light streaking,but no red. I took a clear blue digital ovulation test on March 24th and it was at peak fertility. That was about 2 weeks ago so I'm assuming this is my period?? What was your first period like after a miscarriage?
