Clomid is best if everything is ok with you

I hv regular cycle (32 days). Generally ovulation happened on cd 18/19. I hv been trying last few months but nothing happened. So OB suggested me for clomid 50mg from next cycle. Is it harmful to my body? Im scared by reading -ve reviews of clomid.

Today is my cd 13, got bfn😰 af is due on tomorrow. Plz help me ladies should I try naturally or take a help of clomid🤔
