So, you've just confirmed you're pregnant & you're nervous because you don't know what to expect.
First Trimester Checklist:
Schedule an appointment with your OBGYN - typically when scheduling an appointment, they'll ask when was the first day of your last cycle. This is used to calculate how many weeks you are and your anticipated due date. You will also schedule first trimester genetic screening.
Start taking a prenatal vitamin that contains DHA & folic acid.
Cut down/avoid caffeine - caffeine can be linked to low birth weight.
Stress less - believe it or not, your baby can feel it when you're stressed and your body will feel it too.
Get plenty of rest - you may feel more tired during the first trimester, go to bed earlier or take naps during the day to ensure you're getting enough rest.
You may experience nausea - however, if you're unable to keep food liquid down call your OBGYN as soon as possible because you may have other complications.
Watch what you eat - certain foods aren't good for the baby. Your OBGYN should provide you with a list of foods to avoid during pregnancy. Be sure to look at food labels to ensure that the foods or drinks are safe to consume during pregnancy.
Check your medications - certain medications aren't recommended for pregnancy.
Second Trimester Checklist:
Start your baby registry.
Plan your baby shower/gender reveal and send out invitations.
Get Second Trimester Genetic Screening.
Prepare the baby's nursery.
Attend monthly prenatal appointments (if it is a "normal" pregnancy, you will only see your OBGYN every 4 weeks).
Third Trimester Checklist:
Baby proof your home.
Secure the car safety seat in your car.
Pack your hospital bag(s).
Attend weekly prenatal appointments.
Plan your maternity leave from work.
