Hi and welcome to HCM!
Thanks for posting your query here.
Irregular cycles could be a change in the duration of the cycle-either shortening or lengthening. The cause for irregular cycles could be thyroid
disorders, PCOS, anaemic conditions, improper diet, stressful conditions, fibroids, menopause
conditions or dysfunctional uterine bleeding
To confirm it as a miscarriage
first the pregnancy
has to be confirmed. It can be done by urine pregnancy test or by ultrasonogram. In your case a scan will be helpful. It will diagnose the pregnancy or it will give clue to the cause of the bleeding. Depending on the condition you can proceed with the treatment.Hence get a scan done .
Hope this is helpful to you.
