Do you think I have an infection and how can I tell?
Bad like how? Rotten eggs? Weizen yeast can smell like sulfur (rotten eggs) during fermentation, but it goes away. In fact, most beers change pretty dramatically during the yeast life cycle... a lot of transient flavors and aromas are there that will not end up in the finished beer.
If you do have an infection, it will be much more easy to ascertain after primary fermentation is done. Even then, you should wait to pass final judgement (I think) until bottling/kegging time. Sorry I don't have a better answer... I know it's hard not to be anxious after putting so much work into brewing. Good luck!
