1. A breast pump comprising: a pump; anda conduit assembly in fluid communication with the pump and a breast shield, the conduit assembly including a first connector having a first port, a second port, and a third port, the first port in fluid communication with the pump and the second port,a second connector having a fourth port, a fifth port, a sixth port, a seventh port, and an eighth port,the fifth port in fluid communication with the second port, the sixth port, and the seventh port,the fourth port in fluid communication with the third port and the eighth port, andthe sixth port in fluid communication with the seventh port and the breast shield. 2. The breast pump of claim 1 further comprising a second pump in fluid communication with the conduit assembly. 3. The breast pump of claim 2 further comprising a motor coupled to the first pump and the second pump and configured to control activation of the first pump and the second pump. 4. The breast pump of claim 2 further comprising a third connector having a first port in communication with the first pump, a second port in communication with the second pump, and a third port in communication with the conduit assembly. 5. The breast pump of claim 1 further comprising a solenoid valve in fluid communication with the pump and the conduit assembly, the solenoid valve configured to control the fluid flow between the pump and the conduit assembly. 6. The breast pump of claim 1 further comprising a user interface configured to control an amount of vacuum generated by the pump. 7. The breast pump of claim 1 wherein the conduit assembly further includes the seventh port in fluid communication with one of a second breast shield and the eighth port. 8. The breast pump of claim 7 wherein the eighth port is blocked from fluid communication with the environment when the seventh port is in fluid communication with the second breast shield. 9. The breast pump of claim 1 wherein the conduit assembly further includes a conduit in fluid communication with the third port and the eighth port. 10. The breast pump of claim 1 wherein the seventh port is in fluid communication with the third port when the seventh port is in fluid communication with the eighth port. 11. A method of converting between a single breast pump and a double breast pump, the method comprising: connecting a conduit assembly to a pump, the conduit assembly including a first connector having a first port, a second port, and a third port, the first port in fluid communication with the pump and the second port,a second connector having a fourth port, a fifth port, a sixth port, a seventh port, and an eighth port,the fifth port in fluid communication with the second port, the sixth port, and the seventh port,a first conduit in fluid communication with the sixth port and a first breast shield, anda second conduit having a first end in fluid communication with the seventh port and a second end;selecting one of a double breast pump mode by connecting the second end of the second conduit to a second breast shield and blocking the eighth port and a single breast pump mode by connecting the second end of the second conduit to the eighth port; andactivating the pump to alternate between a first cycle and a second cycle to express fluid from at least one breast. 12. The method of claim 11 wherein the first cycle applies a vacuum to at least one breast. 13. The method of claim 12 wherein in the single breast pump mode air is removed from a first pathway defined by the first breast shield, the first conduit, the sixth port, the fifth port, a third conduit, the second port, the first port, and a fourth conduit between the first port and the pump and a second pathway defined by the third port, a fifth conduit, the fourth port, the eighth port, the second conduit, the seventh port, the fifth port, the third conduit, the second port, the first port, and the fourth conduit. 14. The method of claim 12 wherein in the double breast pump mode air is removed from a first pathway defined by the first breast shield, the first conduit, the sixth port, the fifth port, a third conduit, the second port, the first port, and a fourth conduit between the first port and the pump and a second pathway defined by the second breast shield, the second conduit, the seventh port, the fifth port, the third conduit, the second port, the first port, and the fourth conduit. 15. The method of claim 11 wherein the second cycle releases a vacuum from at least one breast. 16. The method of claim 15 wherein in the single breast pump mode air is transmitted to the breast via a pathway defined by the first breast shield, the first conduit, the sixth port, the fifth port, a third conduit, the second port, the first port, and a fourth conduit between the first port and the pump. 17. The method of claim 15 wherein in the double breast pump mode air is transmitted to a first breast via a first pathway defined by the first breast shield, the first conduit, the sixth port, the fifth port, a third conduit, the second port, the first port, and a fourth conduit between the first port and the pump and to a second breast via a second pathway defined by the second breast shield, the second conduit, the seventh port, the fifth port, the third conduit, the second port, the first port, and the fourth conduit.
