Love. (Long post - sorry!)

I'm so glad this is here - hopefully we're all actually adults lol but I'm looking for some serious advice. 
My boyfriend and I have been together for 3 months (4 on the 12th of November) and we're both in our twenties. We've pretty much spent every day together (and I mean that in the healthiest way possible. Not like when you're 14 and you're inseparable and young and in "love" and it's unhealthy and obnoxious lol)
He's seen me at my worst and my best, and I've seen him at his lows and highs. 
I want to tell him I love him, but I don't know when the right time would be..?
And I know that sounds beyond stupid, but I've never felt this way about someone before, I thought I had felt love before but this is so different.. And that's why I think I'm so confused. 
I'm afraid that I'll say it and he won't say it back, not because I'm in desperate need of hearing it, but what if he's not ready tosay it (which would be fine) but then things get awkward..? That's my fear. 
I'm confident in my feelings for him, but the "what ifs" of his reaction are what are scaring me. My anxiety is definitely getting the best of me here. 
I was thinking of waiting until his birthday, (February) and doing it in a sweet way, but nonchalantly so that its memorable and meaningful but without pressure. 
Any suggestions, or advice? I'm obviously a compulsive worrier. Lmao
