Pregnant?

Patient: My last period was january 1, 2013. My period is now late, I’m getting sick to my stomach at like 4 in the morning, my boobs hurt, I get ridiculously tired during the day and can’t sleep at night, I’m cramping, and I keep getting headaches, and had a uti. I went to the ER for back pain on the 27th and that is when they found the uti but the pregnancy was negative. Could I still be pregnant and that was too early to detect on a urine test??

Doctor:
