Spotting / period?

So my period has been irregular like 80% of the time always (22 years old now) . After almost 4 months of not having period , I started light spotting a few days ago and it has continued to build a bit more to today, but still brown and dark. What do you guys think? Is this my period starting ?

I am honestly asking because me and my boyfriend enjoy sex on my period so he can finish inside me and idk I am just asking opinions lol.
