Help please

7 dpo 
​Af is 2 days late 
​Iv been burping like crazy, dull cramping here and there , excessive peeing, dull constant headache, nausea like crazy, and smelling things that no one else can smell . Tested day af was supposed to come and got a negative and tested this morning with another negative. Me and SO BD every day during ovulation week . Should I wait till 10 dpo to test again? And is it normal to have af and O day only 7 days apart?
