Late period

Hi ladies ok so I had the copper iud it was removed due to the fact that my body started rejecting it. Before it was removed I felt it shift ..now getting pregnant isn't an issue to my husband and I... I'm now 4 days late on my period and I haven't had any pre symptoms to show I'll be getting my period. We've had lots of unprotected sex... I feel like I'm pregnant. Sensitivity to smells and tastes ( I love sour cream and I gagged over it) my nipples are sore.. I'm A LOT more tired then I usually am. I went to the Dr's last week but urine test came out negative. I have been so very nauseous for about a week and a half now. I'm doing my blood test today. What are the chances I'm pregnant?
