Am I pregnant, used a condom! Pls help

Abigail

I din't really record the days I had sex, but he always, uses a condom, yest was my period day and af dint show and I dint get any usual period symptoms like stomach ache, back ache etc

These last 2 weeks ive been feeling dizzy now and then, nausea sometimes, especially when I eat stuff, and stomach feels wierd, and feel very tired.

Is there a chance i cud be pregnant even after using condom, when shud I test?
