7DPO symptoms

I had a a chemical last month & if my cycles are still on track I should be 7DPO today.. I have been having horrible headaches since 4DPO & now I'm feeling so bloated! Lots of CM almost milky like. I'm guessing my period should come between the 15th & the 17th. Not going to test unless AF doesn't come by the 17th. Anxious & nervous. Wondering how anyone is feeling and what your symptoms are around 7DPO?
