Too much of menstrual bleeding after delay, is it normal?

I got my periods after 4 months.

High on stress ofcourse and no pcos or thyroid. Its my second day and I am High on bleeding too. The pads are soaking extremely and I could see clots too.

Clots are not good symbol I understand l.

I will be starting to consume my iron tablets with my vit B12 supplements.

My first day yesterday was extremely painful and I had vomited thrice. The vomit only stopped after me taking the vomit meds.

Today I do feel extremely weak as I am experiencing loss of blood a lot.

About delay in period my Gynecologist used to tell me it's normal if you are stressed and if under 90 to 120 days it's fine.

But I do have a question is it normal (the bleeding part) for women who get periods late?

Any one who experienced it or anyone having vast knowledge about are welcomed.

Thank you!
