What are pros and cons of Birth Control

Delicate

I went to my Obgyn for the first time and so everything went will. I'm just waiting to get my test results. However the Obgyn and nurse keep trying to push me to get on Birth Control and I told them no I dont want it. I honestly don't think I need it.

So my question is for those who have used birth control is there anything that I should expect while being on it and when I get off it to if I want to TTC or is being on birth control worth it?
