Help!!!!

So right now I have a way to get a onesie for when I do get pregnant to announce it to my husband but I’m not pregnant yet. I mean I could be but I can’t test yet because I don’t start for another 10ish days and it’s too early for me to test. I feel like if I do get it ,it would be in a way giving it bad luck with trying for a baby if I buy one before it even happens.

Opinions? Has anyone else bought one before it’s happened
