I've had my implant in since June 2008, and had really irregular periods, so I am now on the pill ASWELL as having the Implanon. I was on the pill before my implant, and my periods were regular... 2 days after i finish the pill, i would bleed. But its been 3 days since i stopped my monthly intake of the pill, and i still havn't come on. I have put on ALOT of weight these past few months, and i have become really short tempered, and recently i have noticed that my breasts have become alot bigger and tender. Is there any chance i could be pregnant when im both on the pill AND have an implant?
