Switching from Implanon to Yaz

Patient: I was on Implanon for 4 months but had may bad symptoms with it including bleeding so I started to take Yaz to stop the bleeding. I took out the implanon 2 weeks into Yaz and continued taking the pill. I am now on the last placebo pill but still have not gotten my period. I have no symptoms. Is there a chance I could be pregnant or has it got something to do with the implanon? It’s been about a week and a half since I took out the implanon.

Symptoms: No symptoms.
