So happy to be a mom!
Donot worry! In the first three months, you only need to have some regular checks, like weight gain, blood pressure, nothing particular. But you had better see a family doctor. Mayby you need to take some folic acid, iron supplements. I think that most of the pregant women need to take folic acid. You can buy them in the Pharmacy. No prescription is required.
Eat better! Take more rest! Take it easy!!!
Good luck with your cutie baby!
