Opk advice

Beans

So I just want to state I know this is not positive and also I am aware LH can be in your system at all times of your cycle.

What i am querying is my period finished 4 days ago, and this appears quite dark so soon after my period, is this the norm in a 'normal cycle'

The reason being is cause my cycles are extremely irregular and usually opks are very faint for weeks (my cycles can be anything from 40-75 days). So to see this so dark after my period just made me wonder could my medication be regulating my cycles 🤞🏻
