Clomid question

Been trying to concieve for 8 yrs
Just got diagnosed with pcos 
I also just started my Very FIRST ROUND OF clomid ,,and hopefully my last ,,lol 
I'm taking it cute day 5-9
Currently on my 4th pill , I will take last one Tommorw ,
Question is : I have no side effects from clomid so far ,, Does this mean it's not working. 
What are Y'all's thoughts ?
Thanks 😃
