Pregnant – roller coasters?

Patient: I just found out i am pregnant today. Unfortunately I leave for universal studios with my family in a week. Can I still ride the roller coasters?

Doctor: Hello,Thanks for the query.As you have been diagnosed pregnancy now, hence it is best to avoid any form of jerky rides during early first trimester of pregnancy as they would only increase the chances of a threatened abortion. So it is advised to avoid roller coasters.Hope this helps.Regards
