My ob gyn is not doing any hcg test. She said they will see me at 8 weeks for ultrasound and if everything is fine on that then there is no need for hcg. Im in week 5 right now. Just have missed period and 3 positive preg tests.

What should i do?? I don't have any such symptoms and I'm worried that everything is ok or not. What should i do?

Its 1st baby and no previous history.
