Considering to stop tracking :( ??

I came off the pill on around 20th august I waited till 23rd sept for any kind of bleed which was so light but lasted about 10 days very annoying that stopped now again only about 10 days after I am bleeding so lightly again! I now have no clue where I am in my cycle don't know what to do think I'm just gna give up! Has anyone had same problems after coming off pill
