Can Cilest Have Side Effects?

Hi, ive just started taking the pill cilest after a 3 month break from not being on the pill, previously i was on yasmin. I take this an hour before i go to bed but for the past week or so i think ive started experiencing really bad indigestion in the middle of the nite to the point of where its waking me up, Is this normal for this kind of pill and will these side effects subside?. thanks
