Girls, Does birth control make you tired at first and kill your sex drive in your own personal expierence?

My girl went on the pill which is good for us now cause while we do want a family eventually we are fresh out of college and just bought our first house together and settling into our new jobs. So condoms aren't really as good an option anymore since we were sleeping together and having sex nearly every night and the pills cheaper since we have insurance that covers a good portion of the price. Ever since she has been on BC (for about a month) she has said she is tired and napping a lot more and doesn't have the urge or energy to have sex at night.
