Tiny Pencil thin stools or flat ribbon like

[Amybarn38]

I was told years ago i had ins-c. I always had constipation my whole life. This time it was 3 weeks with nothing coming out so i took miralax for a couple days and then had a lot of diarreha so i stopped the miralax and 2 days layer every morning i wld go to the bathroom but it wld be long very thin or flat ribbon like. I still feel bloated and uncomfortable. Im so scared about the ribbon stool because everything online says cancer or blockage. Im a 38 yr old female. Also i started the miralax again last night but havent went to the bathroom yet. My dr cant get me in till tomorrow. Anyone else get this kind of stool with these issues after miralax or constipation? Thanx for any help
