to drink or not to drink?

So my husband and I have just started TTC. I have been on the implant form of BC for 3 years, had it removed in Jan, started the pill BC in February and have only completed 1 full pack before deciding to try for baby #2. I have not taken a pill in about 2 weeks. My friend invited me to her house tonight for girls night and I would like to join in on the drinking part. I'm not supposed to start my period (I think) until next week and my husband and I haven't had sex since Tuesday. Do y'all think it's okay for me to drink a little tonight????
