Is this normal?

I’ve been checking for pregnancy so I’m on Nora be and I missed my period for two weeks then finally got it and then stopped for 6 days and started bleeding again my chart looks like this

The s stands for spotting and the l stands for light bleed

The past 3 days it’s only been mjxed with my pee when I use the bathroom and very light spotting on my pad. The blood seems to be dark red/brown this time. I’m not sure what’s happening. Does it sound like irregular period?
