TTC & alcohol

Betty
Could do with some friendly advice. Me and my hubby are TTC (this is only our second month). According to my fertility tracking, I ovulated on Thursday so this past week has been my fertile window so me and the hubby have been active this week. I haven't been drinking alcohol when trying to conceive so far - just had a few glasses when on my period. Today we are going out for a friends birthday so obviously everyone will be drinking. I don't know what to do because I don't want to do anything that could be detrimental to conceiving but I also don't want the unnecessary suspicion and questions that will come with not drinking! Any suggestions?
