I was on the desorex pill first for 3 months and I experienced really irregular bleeding, way more often when I wasn't not on the pill. However when I went to the doctor i got given cerelle because the clinic I got my pill from first didn't write it on my records and I forgot what I was on. I was wondering another girls experiences on cerelle? I haven't had any bleeding on this one yet and I've been on it 3 wreks which I think is odd because I used to be bleed often on the other pill
