Birth Control pills

J
Hi everyone, 
Suggestions from your own experience 
I am concerned about taking birth control very seriously 
I lost my virginy few months back 
I have had sex with only with person 
Everytime we have had sex i make sure that we always use the condom
I am considering to start taking the birth control pills but i have heard that they cause side effects 
I havent had sex for two months now and if i have plans to getting back with him i would like to start being more careful 
How was your experiance when you started with the birth control pill?
