I have a white, oval pill with IP 109 imprinted on it and I don't know what it is?

It's a Norco

Pill imprint IP 109 has been identified as Acetaminophen and hydrocodone bitartrate 325 mg / 5 mg.

Risk cannot be ruled out during pregnancy. Acetaminophen/hydrocodone 325 mg / 5 mg is classified as a Schedule 2 controlled substance under the Controlled Substance Act (CSA).
Sounds right any questions talk to your doctor or pharmacist.
