Pregnant on mini pill

[lisajarbon]

Hi, not posted before but wanted some advice. I have just found out I am pregnant but have been on Cerazette mini pill for 3 months. I never missed a pill and have no idea why it failed. I take anti-epileptic medication but the doctor would have warned me to use extra protection if that would have affected it surely? Now the baby's father is accusing me of tricking him and trapping him and refuses to have anything to do with me or the baby. Has anybody else gotten pregnant on the pill? Please need help
