What should I expect?

J
Hello, everyone! I started my period on Monday and I am planning on taking birth control pills when it is over. I went to Planned Parenthood and they gave me a brand called Aubra. However, I read reviews online about this brand and they are mostly negative, so I am kind of iffy about taking them. 
What should I expect when taking BC pills for the first time? Thank you in advance for your feedback!
