Urgent help me!

My periods have started to become irregular (its late about 10-30 days) and now my period this month is only 3 days late but everyday I’m bleeding brown. I know it’s old blood but is that bad when it’s everyday and there’s no new blood? It’s been like this for 4 days and I don’t have insurance to go to the doctor.

I really need your help! Thank you so much!
