SHOULD I ALWAYS TELL MY HUSBAND IM OVULATING BEFORE HAVING SEX?

Evelyn
So I'm more than ready to have a baby however my hubby isn't completely ready. He wants to wait until he's making more money. I totally understand him but it's still hard for me. 
When we talk on this topic he says "babe I want a baby but I just want to be making good money before we have one but if it happens I'll be more than happy". Honestly though it won't "just happen" I'm tracking my cycle like crazy I know exactly when I ovulate so as long as I'm doing that it won't happen until we actually are TTC.
I've talked to some women in my life and I told them how much I want a baby but hubby isn't completely ready and they just keep telling how he's never gonna be fully ready and he'll be ready when he finds out I'm pregnant. 
We had a pregnancy scare once and I was freaking out because I didn't want him to stress about money now since he said that's the only reason he doesn't want a baby now but he was so calm about it and even teared up he said he was more than happy. 
Idk should I just not tell him when my ovulation is or should I just stop tracking my ovulation and "let it happen".
