Pregnancy test result!

Good afternoon Dr A few days ago I was feeling sick, dizzy, pain below the navel, then I did the pharmacy test, and tested positive, but today I did the Beta Hcg and the result was that the result was 14mui / ml. Reference 25 mIU / mL or above compatible with pregnancy. Isolated hCG dosing may not establish the early diagnosis of pregnancy. The evolution of hCG levels aids in diagnostic clarification because there is a 1.6 to 2 fold increase in the initial value every 2 days for the first 28 days in most effective pregnancies. MATERIAL: SERUM METHOD: QUIMIOLUMINESCENCE - CENTAUR XP - SENSITIVITY 2.0 mIU / mL The possibility of being pregnant?
Expert answer:

The exam you have done is saying that you are not pregnant, this test is very sensitive and tends to be positive around one week after the pregnancy occurs. Bottom line: At first you're not pregnant.
