Do irregular menses hinder normal pregnancy?

I am a 35 years old boy going to marry a 30 years old girl. Although she is normal, her menses are not regular. Will she conceive normally or not? Further, on getting tense, her nose bleeds. Is that also a problem? Please guide me.

 

Even if her menses is irregular, she can conceive naturally. Getting pregnant has no connection with regular or irregular periods. Also, nasal bleeding has no connection with menses bleeding.
