Start regular exercise

Pregnancy is normal and you are not ill. This is such an important point that most women forget. You must take care of yourself but this does not mean that you should stop all the activity in your life.

Women who regularly exercise during pregnancy do not have to face many complications in the end. If you haven’t started regular exercise during the first four weeks of pregnancy, maybe this is the time. Keep yourself fit and active to keep your blood flowing and your body healthy.

Quit unhealthy habits

If you are a smoker or an alcohol consumer, you have to stop for your baby. Alcohol and smoking can have very bad effects on the development of a baby. You might not want to do this for yourself, but quit these habits for at least these 9 months to come.

Is it the time to announce the pregnancy?

This is just the beginning, and announcing your pregnancy is not the thing that you should be doing by now. You must tell your partner and both of you can enjoy this time by yourselves.

Announcing pregnancy can be stressful at times and any complication can make you disheartened as well, now that you have to tell all those people too. Keep yourself from this extra stress and wait for a few more weeks until you announce the good news.

Booking an appointment with the doctor

If you haven’t consulted a doctor by now or you just got to know that you are pregnant, the first thing that you should be doing is to get an appointment for yourself. Although it is just the beginning but your appointment must be to confirm your successful conception and understand if everything is going well or not. You cannot watch your baby by now. You still have to wait a few more weeks and this wait is worth it.
