I think might be too early. This never happen on me. But happen to my friend. She tested positive before her cycle was due. Maybe 3-4 days early. She went to visit my gynae for 3 time. At the 4th visit gynae use Transvaginal method after blood test & found the LO. Each visits was a week interval. By then she only 4 week plus pregnant. Just wait a little more. Got to let the baby to grow. All the best!
