Hi I wonder if you could help me. Period late by 20 days Intense heat in face & forehead spells dizziness, bloating spells Fatigued not pregnant (test)?

Probably different. Most likely the late periods is not related to the other symptoms although undiagnosed hyperthyroidism is one possibility. The most efficient way to handle this is to see a primary care doctor to address the most pressing issue of heat in face, dizziness, fatigue and bloating. After that has been treated an obgyn can help you with menstrual cycle regulation.
