Blood test

Cassie • Have been trying to get pregnant for 6 years Hoping i dont have to wait to much longer its driving me crazy!

I went to the dr to do a blood test. The app says im 4 weeks pregnant today and i have gotten 6 at home pregnancy tests but my hcg levels only read 14. My dr said anything under 25 is considered negative. Is it possible its still just early and i am pregnant ?
