2 years post op implonon out

I was woundering if anyone else out there had the implonon bc and hd RNY bypass. I got my implant out about 3 weeks ago. We are trying to have another baby. I got pregnant 6 months post op with our first child. I have gained about 10 pounds back. I had/have PCOSand am scared of it comming back. Has anyone out there been in my shoes? How long has it taken to get pregnant after the implant was taken out. Please let me know I am not alone.
