Help????

I'm 15 DPO. I've been super nausea, crazy bad headaches, really bad heartburn, indigestion, really bad back cramps, and my face has been badly broken out for 3 weeks. Tested at 6 DPO and 11 DPO(both negative). Now I've started throwing up early in the morning and my boobs have become so sensitive that they hurt even if they are brushed up against. I went to the doctor on Monday and they did a pee test and it was negative. I'm officially 2 days late as of today, with no signs AF showing up. Should I wait a little longer and take an other test and a blood test????
