I had been feeling sick all day Saturday

I had been feeling sick all day Saturday. Saturday while playing cards fr shot, I took 3 shots. The first two shots went down easy but when I got to the third one I was gagging. I felt sick for the rest of the night. Woke up out a dead sleep Sunday morning and rushed to the bath to throw up but nothing came out! My brother was boiling food and I was trying to eat it but my stomach would be agree. So went to the Dollar Store, brought the test and read Pregnant 2-3 weeks
