Irregular bowels for past few weeks

Digestive health
1

Several weeks ago started having hard stools with white specs in them . If I had looser stools, no white specs . I had one night of cramping and ten diarrhea . Went away but seemed to get backed up again. So Sunday evening decided to take Dulcolax to help move things . Had the worst pain ever that night . Don’t recommend it . Almost passed out . Anyway, since then, my bowels have been very loose . Yesterday seemed almost normal but today , I’ve been to the bathroom at least 5 times . I suffer from anxiety and this makes me think I have Colon cancer . No blood , no thin stools . Mainly irregularity and very noisy stomach , I had a colonoscopy 4 years ago and no polyps were found . I just want to stop worrying . Can’t get in with my gastro dr. Until mid June . Any feedback would be greatly appreciated ! Thx
