Is a high haital hernial connected to crohn's and an irregualr period?

[mercadoo4]

I am 18 years old and at the age of 16 I was diagnosed with a high haital hernia and acid reflux. I am no longer experiencing the crippling amounts of pain as I once did, however some days I will experience small amounts of pain.  However, my father and two of my cousins were diagnosed with Crohn's disease and I was wondering if my high haital hernia could be connected in some way and if I should get tested fro Crohn's just to be safe.

Also, I have been suffering from severely irregular periods. I have gone to doctors and they cannot explain why my periods are so irregular. Some months my period would last for an entire month and others for a week with vommiting.

I was also wondering if this is connected in some way.

Lately I haven't been eating as much as I usually have
I sometimes wake up in night sweats
occasionally my weight will drop from 98lbs to 96lbs (i am a naturally skinny person my doctors have comfirmed this)

In any event could these three be connect?
