paraguard iud copper (removed)

Lisa
I took out my IUD May 1st and I am currently TTC. I had my first IUD in for a little over three years maybe four I took it out to give my body a break and we placed it two maybe three weeks later and place the second one August 2015 and removed it this year. This will be our first child together... how long did it take for anyone to become pregnant after this particular birth control? I also have it. This same month I took out my birth control it was pretty regular just a day or two shorter
