I need help please

Ladies I need some help I know that this is for a doctor to deal with. And I have an appointment set up but in the mean time.

Since my son was born 5 years ago I've been irregular no periods for months or 3 week long periods. So recently I have started getting my period more frequent like once a month. We'll this period this month is weird. I drank red raspberry leaf tea to try to regulate my period well I think it just messed it up more! The first period was a light 6 day period but then I got spotting a day after I finished my period and it keeps going every other day I get a period or I'll skip 2 or 3 days then I get a period. But it's only ranges from one day or 2 days followed by cramps and back aches then I'll stop. It seems like every other day or to days I'm on my period again! Anything that I can take that will help? Or has this happened to you what did you do about it? Advice would help
