Finding out you're pregnant can be one of the happiest days of your life. But it doesn't take long before the emotional roller coaster begins - filled with anticipation and anxiety.

New moms often begin to wonder, now what? In this month's Pregnancy 101 report, Serese Cole tells us what expectant moms should do once they hear the news.

It's Jamie Kernan's third pregnancy but she still has that new mom feeling.

She says, "From the moment you get that positive pregnancy test, it's like - OK, I'm going to do everything I can to make sure you're OK and get you here safely."

For Jamie that means a healthy lifestyle so she plans to, "eat well, avoid all those hazards that were hazards before you got pregnant - smoking and alcohol, but most importantly staying active."

Dr. Tom Martin says Jamie is on the right track. He says once you find out you're pregnant, you should first visit your OBGYN.

Dr. Martin says, "One of the biggest reasons for seeing the doctor in the first 12 weeks of pregnancy is to establish their due date - figure out how far along they are."

And if you're not on them already, doctors recommend once you find you're pregnant to start taking a good prenatal vitamin. It's not only good for you, it's good for your baby.

Dr. Martin says there are a number of good choices out there. The key is making sure you get enough Folic Acid which reduces the risk of miscarriage and birth defects.

Next, focus on eating a balanced diet, limiting the caffeine and the seafood.

Dr. Martin says, "The CDC recommended that pregnant women not eat more than one or two dishes of seafood a week."

Jamie's bundle of joy should arrive in January. This time, she's keeping the sex a surprise.

She says, "When we went to that ultrasound, I just wanted to know that all the fingers and toes were there and that everything else looked fine. And it did."

And that's welcome news for any expectant mom.

Exercise is also encouraged during pregnancy. If you have a regular exercise routine before you get pregnant, you should be able to maintain it. If you're just getting started, take it slow and be careful not to over-exert yourself. It's smart to discuss your exercise routine with your doctor.
