Pregnant?

I Stopped My Period Sept. 13th. After I Was Spotting Light Brown, Then A Whitish Discharge, When Dried It's Yellow/brownish. I Feel Nausea Every Morning I Wake Up, Tired, Sharp Pelvic Pain. Now I Stopped Spotting, I Have Off And On Cramps (Nothing Major) And A Lot Of Farting. Could I Be Prego Or Ovualating?

We BD Day Before Yesterdsay Incase I Was Ovualating. Last Night And This Morning. No Bleeding Or Anything. Still A Lot Of Farting, Belching, && Lil Cramps.
