Welcome here. This is very reassuring that you had normal smears for 10 years after loop treatment. I shall tell you some facts that may help alleviate your anxiety
but SHOULD not cause you to loose your follow up smear again.
CIN-1 may spontaneously regress in at least 50-60% of women within 2 years. Malignant potential is very low but still 10 times higher then women with normal smear ( So, follow up is essential).
I wish you get a perfectly normal smear & stay happy & healthy with your baby. All the best.
