TWW wait drinking-feeling guilty!

I normally don't drink much while TTC, but we had our annual 4th of July party and I got drunk from the delicious Sangria we made. I'm now 8 dpo and can take a pregnancy rest this week. I know I'll feel guilty if it's a BFP. I've miscarried before so Im worried. My DH says don't stress. I mean, I did make the choice to do it. I have other friends who admitted they drank before they knew they were pregnant. Anyone else have a similar story or going through the same thing? Thanks!
