Estrogen?

Is anyone familiar with high levels of estrogen and getting pregnant? I had my labs drawn at 5dpo and got an estrogen level of 162 (is within range but my NP is saying it’s high) she also asked “could you be pregnant?” And I said yes. But I haven’t gotten a positive HCG, my period is due tomorrow, and I had been having 28-30 day cycles. This one will be 33 days of AF shows tomorrow, but it’s doesn’t feel like my period is coming.

Any input is helpful!
