Hi
Thanks for posting on HCM
No period for 6 months could be caused by
pregnancy or other medical conditions out of pregnancy.You have not told us if you are pregnant or not.I will answer you question in both ways.
-If late pregnancy, possible causes could be placental detachment and
placenta previa.Other causes will not give much bleeding.
-Out of pregnancy, possible causes of delayed menses and abdominal cramps include: hormonal imbalances,
Polycystic ovaries,uterine scaring,
contraceptive pills, medications, low weight, excess exercise, stress.With no period for 6 months, feeling pains/cramps and increase in volume of menses are common findings.
No matter the cause, you will need to see The Doctor or a Gynecologist for examination and work-ups.A pelvic
ultrasound will be very useful here.
Hope my answer will help you
Best regards
