Doctor's answer:
A possible reason could be a short gestation period, making it difficult to see a gestational sac. It could also be due to poor fetal development, leading to bleeding. Another possibility is an ectopic pregnancy. In this case, it's important to visit the hospital for an HCG test and also check the progesterone levels.
