After takeoff; the #1 [Flight Attendant] and I started smelling something foul. The # 2 [Flight Attendant] called the #1 [Flight Attendant] to see if all crew was smelling the same thing and the cockpit pitched in saying they were smelling something pungent as well. At first; the pilots wanted to continue on but when the smell kept coming back; they decided to head back to ZZZ. The #4 [Flight Attendant] felt nauseous and threw up; the #1 [Flight Attendant] had a headache; [and] the flight crew had a headache along with itchy and dry eyes. I felt nauseous and had a severe headache with heat flashes. As a team; we decided to go to the ER to check ourselves out.
