AF over 6 weeks late?

[Smellyoulater]

It's been over six weeks since my last period. I've done multiple PTs and all negative (though last intercourse was April anyway and I have the coil so unlikely)

I wonder what's causing this? I am like clockwork usually. I've not had any more stress than usual, or illnesses. Is this something to worry about?

Could be lots of things.

Are you very slim and active?
Could you be menopausal?
Could be a medical condition such as PCOS.
Could be a hormonal imbalance.

If you are concerned, go to your doctor. They can do the required tests.

Thyroid? Can cause changes in cycle.

Mirena coil? No periods common with that
