Hi Dr. I am 4-5 weeks pregnant coz the PT shows positive. I just had a TVS yesterday to confirm my pregnancy however nothing found, had a thick endometrium and no free fluid in the cul-de-sac. the sonologist suggested that it shall be correlated clinically with beta-hcg test. Hence, I had the beta-hcg test yesterday and the result was 1500. Am I really pregnant? Maybe it is just too early to have TVS? please help me with this.
