The Hunger Games star Elizabeth Banks has shared her personal experiences with birth control in a candid campaign advertisement for President Barack Obama.

In a new promo aimed at female voters, the actress tells how she turned to the non-profit organization Planned Parenthood for health care services after she graduated from college and had no medical insurance.

She says, "Yes, I got birth control, but it was for my massive migraine headaches and my heavy flow. Yeah, I'm on record saying I had a heavy flow! Unfortunately, these are the type of things that I don't want to discuss with employers..."

"That's between me and my doctor, and at the time, my doctor happened to be at Planned Parenthood. I'm really grateful that they exist, they provide essential services for women all over this country."

Banks goes on to stress the importance of federal funding for the reproductive health clinics, which Obama's Republican rival Mitt Romney opposes.

She adds, "President Obama has not compromised on women's rights, and that's why President Obama needs to stay in office."
