For About A Day And A Half Now Right After

For about a day and a half now right after lunch yesterday I started having random pain in my stomach (all around the abdominal area), bloated with gas, loss of appetite, feeling nauseous and I feel a headache. I am currently menstruating, but the only usual symptom I get are the headaches. I am a daily coffee drinker and have not had any for the past three days. Also three days ago I went binge drinking and puked.
