If you're already pregnant, or if you're planning on getting pregnant soon, you may already know a little bit about what occurs during your pregnancy. You may already know that some of the things you usually do aren't going to be able to be done until after you've given birth. There may be some things that you weren't aware of though. Read on for a few of these things.

1. Caffeine

Caffeine can raise your heart rate and cause your baby's heart rate to raise as well. If you drink a lot of coffee, energy drinks, or other caffeinated beverages, you need to limit your intake after you find out you're pregnant. One cup of coffee is not that much caffeine, but more than one cup or a large container of coffee can be dangerous for your baby's tiny heart. If you still want to drink coffee, you can switch to decaf instead and skip energy drinks altogether.

2. Strenuous Exercise

Strenuous exercise can be dangerous for your baby and can lead to a separation of your uterus. Some exercise is good for you and can also be beneficial for your baby. Exercise can also keep you healthy and in shape for when your baby comes home and for your delivery as well. Strenuous exercise such as cardio, spin class, or weight lifting can all be too much as you get further in your pregnancy. Talk to your obstetrician about your exercise routine and if you can continue to do that type of exercise. Some stretching can also be dangerous, so be sure to consult your obstetrician about doing yoga or Pilates as well.

3. Flying

You should be OK with flying during your pregnancy, but if you're a high risk pregnancy, consult your obstetrician first. During your third trimester of your pregnancy, you shouldn't fly no matter your pregnancy. Flying during the third trimester is dangerous for you and for your baby. Not only is the pressure from flying dangerous, but being up in the air and away from your obstetrician or your family in the event something does happen can be very dangerous.

Throughout your pregnancy, there are things you should and shouldn't be doing. Always consult your doctor of obstetrics first before doing anything especially if you aren't sure about it. Don't put your baby your yourself in any unnecessary danger. You want your pregnancy to go along stress free and without any issues so you give birth to a happy and healthy baby.
