Anyone have success ttc after Paraguard???

Courtney • 37 years old, married with stepkids. BFP with 🌈 after first IUI and due October 2017!
36, ttc #1 and when the IUD was removed it was a bit "stuck" and my OB commented, "I'm surprised it worked." I heard: "You're not able to get pregnant; this was faulty..." Please somebody, tell me something good. In the tww of our second cycle trying.
