HELP NEEDED

im 15 y/o and have been taking two AZO cranberry gummies daily( just to boost my health i don’t have a uti ) or anything. for about two weeks now. i started to notice when i wiped i was spotting but my period isn’t close and starts somewhat on the 9th. today I’ve figured maybe if i take only one it’ll stop but I notice it wasn’t as much as spotting it was like my cycle was just starting. please help should i change my brand choice or not take cranberry pills unless needed?!
