I'm 31 have 4 kids i have had irregular periods for 18 months keep having hot flushes and mood swings why is this ?

Difficult: You r under stress and the question is whether the hot flashes r related to ov. Hormones. Your periods are irregular which means your cycles are irregular but it's likely not menopause, your too young. You could get on the ocp to regulate the hormones but my guess is that that won't do it. The thyroid or anemia could be it.. Do you sleep well? Crying spells? Panic attacks? I think anxiety.
