I’m pretty sure this is negative..

I had my mirena removed just over two weeks ago and had what I thought was a period straight away but now I don’t know?

I have done cheap ovulation sticks and nothing has really changed on them and my clear blue advanced sticks have said I’m in high ovulation but not peak yet for 5 days and tomorrow will be the 6th day..

I have had headaches the past 2 days and feeling on and off nausea but have done a PT aswell and I’m sure that’s negative?

Any advice welcome!
