Pregnant?

Ok so I saw my gyn a few weeks ago right before ovulation. Got an ultrasound and blood tests to check everything. The ultrasound tech told me my right ovary was getting ready for ovulation in a few days (my periods had been oddly spaced so I was missing the ovulation days) so the gyn tells me if I don't get my period a couple days after Xmas take a test if it's negative wait a few more days. So today is day 33 in my cycle and 15 dpo still no period and couldn't take a test until late in the day after I'd already peed like 100 times lol so it was negative but I'm like 💯 I'm pregnant. I knew with my son and I just know but I'm scared to confirm it. Should I wait another few days or take a test in the morning?
