clomid question

Kimberly
I have pcos and am taking clomid, this is my second month trying it, I have a follow up appointment in July and my obgyn said I should be pregnant by then. I found out about my pcos in April and am also taking metformin. 
Anyone have any tips on when I should have sex after taking clomid? I have 5 pills I take after the 5th day of my period, which started this morning and is triggering my question. Thank you 😊
