Coffee while TTC... is it okay?

I know this has been asked many times but I am just going to ask again. Is coffee okay while TTC? I've tried to cut it out but the days I don't have a cup in the morning, I literally can't function lol. I only have one 10 oz cup in the morning with a bit of hazelnut creamer. We have been trying 9 months and nothing so I'm willing to give it up if it does cause issues, but it's so hard!
