Hello, Just wanted to say hello we are in almost the same boat, I removed my IUD Monday the 28th. We are trying for our 3rd child as well with our kids (boy and girl) 7 and 8. My doctor told me as well that it can happen immediately, however for me I didn't have periods on the IUD so the hardest thing for me right now is not knowing when ill have a period or figuring out my ovulation. Good luck to you!
