Because your pregnancy is considered high-risk, it's important to work with your doctor or care team to get any health problems that can be managed under control.
Other tips for a healthy pregnancy include:
See your doctor early on and throughout your pregnancy for prenatal care.
Eat a healthy diet (getting plenty of fruits, vegetables, whole grains, lean meats, etc.) and exercise if your doctor says it's OK.
Gain a healthy amount of weight (not too much or too little).
Protect yourself from infections (including Zika). Be sure to wash your hands well and often; not eat raw meat, fish, or unpasteurized cheese; get any immunizations your doctor recommends; and use condoms to protect against STDs.
