Exercising while ttc

Sedaya • My name is Sedaya and I'm 23. My husband and I have been together since 2009 and got married April 2015. We have a four year old daughter and had our second daughter 4-16-16 :)
I recently started going to the gym to get healthy before my pregnancy however I'm wondering if I am pregnant should I take it easy? I'd like to continue going throughout my pregnancy but I'm not sure how hard I should do it in the gym.
