Do you think my BBT could indicate a hormonal imbalance or potential problem that I need to see my GP about?

I’ve noticed that the spotting (red dots) is increasing in days before my period starts. And every cycle I trick myself into thinking that it could be IPB.

The spotting in this cycle started from 6DPO and I had a BFN this morning (11dpo) and the big temperature dip today usually means that I’ll get my period later today or tomorrow.

This also confused me as my LP phase has been bang on 15 days every cycle so it seems to have now reduced?

I went to my GP but she told me to go away until it had been a year. I had my mirena coil remover last June. Feeling disheartened
