when do you think I ovulated?

I got a still happy face on October 2nd. We tried those few days before and after. I'm estimating I am 11-12dpo. What do you ladies think? I'm due for my period October 19th as I have a 30 day cycle. I have had light cramping and a pinching sharp feeling every now and again. No tender breast and no fatigue. I took a test yesterday morning it was negative. I was thinking of taking another tomorrow morning with my fmu. What do you ladies think?
