Confused/concerned

I had my last period on 9/13/15.

I'm on the mini pill jolivete.

Had spotting on 10/4 & 10/5. After that nothing.

I had prego symptoms for a few days/a week, but now it's almost nothing. Sometimes I do get nauseous from smells and I have cramping, I have been told I am more crabby (I haven't noticed it though)

I am anywhere from 26-29 days as a cycle average. My longest cycle was 53 days.

I am currently at cycle day 54.

Sometimes I go to the restroom and it smells (ik tmi) like I have my cycle but there is nothing other then white/clear discharge.

I have mentioned it to my fiance and he's like "you've been late before, and you weren't prego"

I took a test on 10/17. Which was negative.
