When should I test?

Sophi

TTC for 2 months after 5 years on mini pill. AF is due in 3 days according to app but I was very irregular during my time on the pill.

For the last week I have felt very nauseous, it has got even worse today especially when I eat or think about eating. Not sure if this is an early sign or if I am thinking too much into it

Is it too early to take a test?
