Ovulating and anniversaries?!?!?!

Sooo, my SO and I have our anniversary coming up on Wednesday, and lucky enough it happens to be the day before I’m supposed to ovulate. We lost our first baby on the 2nd of this month and have been talking about trying again right away and haven’t been careful at all so far. We got an okay from doc to try again after the bleeding stopped because I was so early my body kind of bounced back. My thing is my sex drive is through the roof!!!!!!! And he’s the kind of person that likes it but not as much. He already told me we could do it (it’s kind of a traditional thing) but I need help!!! He’s always wanted a baby born on his birthday and if I were to get pregnant now it would be born right around that time!

My question is: Am I wrong to not not tell him when I ovulate even though we’ve had extensive conversations about it the past couple weeks and make it a surprise? Or should I go ahead with it? I do love him and don’t want to think I’m making a selfish choice.
