Should I tell my husband I sneaked a peek at baby's sex?

TLDR - I know baby's sex and husband doesn't know I know - should I tell? We were trying to wait for surprise like we did with our first.

Hey ladies - I did a bad thing today.

Hubs and I didn't find out the sex of our first child, a boy and decided to let it be a surprise again this time.

I am 33 weeks along now and have been so good at looking away at every sono and even not looking at the early genetics results.

Well, yesterday I found out that not one, but two of my cousins are having boys. I have a boy already and my one other cousin who already has kids has 2 boys. I was suddenly convinced this whole next generation of cousins will be all boys and needed to know.

I had a envelope with hundreds of papers, my whole chart because I needed to switch doctors. I have had it just sitting on my desk for a month.

I thought the sex might be in the chart somewhere but wasn't even totally sure. This morning I sat and looked through every paper until halfway through one said XX. It is a girl.

Now I feel sooooo guilty having this secret and not having the willpower to just wait a few more weeks.

Should I tell him right away that I know? We've been arguing a lot lately so also worried it will make things worse.

Should I just keep the secret?

Or should I admit I know when labor starts so he can't really be too mad and I don't have to fake surprise in the delivery room (I am not a good liar).
