Destiny
I began to have frequent urination and severe nausea so I visited my Drs and took a pregnancy test. Well it said negative so I left a few minutes later and As soon as I got home I received a phone call from my dr saying it showed positive after 10 min. He told me to get a blood test done so I went to the er and we took a urine one first and it had the faintest little line ( which makes sense seeing as I'd only be 2 weeks along now.) and we did a blood test and they said a non pregnant female should be able a 0-6 and I was at a 36 which means I'm early in my pregnancy
