There's new evidence that two popular birth control pills may put women at a higher risk for blood clots.

The oral contraceptives, made by Bayer, are sold under the names Yasmin and Yaz. Researchers writing in the British Medical Journal said the pills contain a newer type of progestin.

Women who took contraceptives with the newer form of progestin had double the risk of non-fatal blood clots than women who took pills with the older type.

Bayer said in a statement that their pills are safe.
