What Causes A Tiny Gestational Sac On Pregnancy Scan?

Hi, I have recently found out i am pregnant, i went for an early scan maybe about 4-5 weeks pregnant they saw a tiny sac but then went on to say they would need to do blood tests as it may be ectopic or miscarried my bloods came back but i just wanted some more advice on my blood results, they came back at 1.641 and 76.9 what does this all mean and is it normal?

Hello,
I have gone through the query and understood your concern. I will be able to comment further if you can elaborate on the blood test performed. If the value of 1.641 indicates serum beta-hCG, this suggests non-pregnant state. In an ectopic pregnancy, usually the gestation sac is located outside the uterine cavity; sometimes an empty sac may be seen in the uterus simultaneously. To know the viability of the pregnancy, you can repeat the sonogram through the trans-vaginal route after another week. If the fetal pole is visible by then along with cardiac activity, things are going fine. Hope this helps.
