Weird symptom with birth control...anyone else experience?

Elizabeth
So my doctor prescribed me microgestin fe 1/20, and I've been on it almost a month. I've noticed the past two weekends that after having 2 beers max, I wake up the next day nauseous in the morning and then after 20 minutes it goes away, which is not normal. Has anyone else experienced anything like this? The only time I feel this way is after I drink a beer or two, and I know it's not a hungover feeling.
