Hi Doctor. I Just Wanna Ask. It Is My First

Hi Doctor. I just wanna ask. It is my first time to take althea pills, and i am on my 13th day today and i am having spots now. Is it normal doc? Should i continue taking althea if in case my mens come or should i take a break? I still have 8 tablets left. My mens comes every 28th of the month. I have an irregular cycle. Sometimes it comes after 2-3months. Thank you doc. God bless.
