Hi, I am 24 years old and got married 6 months ago. I am having pcod problem. My last period was on 6th april. I went to gynaecologist on 24th May and through pregnancy test kit it had shown positive result. She did transvaginal ultrasound but there was nothing visible in it. She asked for follow up scan after 15 days. I am getting pain in my lower abdomen sometimes. When would be fetus or sac visible in ultrasound? I am really very worried about it as it is my first pregnancy. What I should do now? Should I go for ultrasound now or should I wait until 15 days?
