Anyone use the patch ?

I was on Depo after having my daughter but switched to the patch about 4 months ago. My daughter will be a year old on new years. And we have decided to try and have another baby . So. I had my no patch week . Put a patch on Monday and took it off on Wednesday because we are for sure trying. But now I'm bleeding again. How long is this break thru bleeding going to be going on ? Also how long has it taken others to get pregnant ?
