Answer:
I knew I was pregnant within 3 days, because of nauseousness and vomiting. Blood work confirmed pregnancy and the blood work said I was in my second trimester, which was impossible, I had been single for 2 years. At 5 days I had an ultrasound to see why the blood work had such a high count of cells, and it was because there was 2 little tiny dots, the size of a pin head, the ultrasound lady told me there was 2, not the doctor.
