My beta hcg level is 2.69 and urine test also negative and also did sonography. But I don't remember the exact date of unsafe sex but it's almost a month. And also don't remember the exact date of my cycle because from last 2 month I am getting period 3 to 5 days late. My Dr. suggest me to take regestrone 5 mg 3 time a day 10 table. I finished it and over 2 days. Still I can be a pregnant. Or any else problem.
