Right time to say I love you...

Soo question ladies when do you think is the right time to tell your significant other that you love them? My boyfriend and I have been together for almost a month but I’ve been through a lot of shit from past relationships to know when I love someone and I really do love him but I’m scared to say it in case it’s to early for him...please help cause he’s the first decent guy I’ve dated and I don’t wanna lose him.
