Ovulation advice

Hey girls, so I’m trying to convince again after a loss in July. My periods have been sooo messed up ever since, ovulation has been messed up like crazy. I’ve had 5 periods in 3 months. I’ve just come off my period today and just decided to test ovulation as I was curious to see how dark the line would be as they’ve all been SOOO light the past few months like hardly even visible but today it’s rather dark the day of finishing my period. What does this mean? I’m new to this🤣 is it normal to be this dark so quick?
