In looking thru posts, I've come across A LOT of ladies asking and wondering if what they're experiencing is IB. From what experts have led me to believe tho, IB is actually quite rare (only occurring in about 20-30% of actual pregnancies). With how rare they say it is, and how often I see women claiming to possibly have it, I wonder... How rare really IS it? So let's take it to the polls! Ladies who have actually been pregnant: Did you experience IB? And if so, please feel free to add a comment and share what it was like for you. Thank you!
