First IVF Guilt

Hello! My wife and I are in our first round of IVF after two failed IUIs and one canceled. We also attempted two at home inseminations. All frozen sperm. A few weeks before we started IVF I barely drank and a week before we started STIMS I totally cut it out. We are on day 9 of STIMS and last night we went to a cancer benefit for a friend and I didn’t drink all night but at dinner gave in and had one glass of wine. I have no known fertility issues, but am feeling super guilty this morning. Any successful stories who had a slip during STIMS?
