they told me this was extremely common and they'd "NEVER" had a problem afterwards.. The polyp is just above my cervix, which would be a very unlikely place for an embryo to implant, but they want to get it out just in case. Since there's no time for another mock, this makes me very nervous. I trust my RE completely and the clinic has very, very good stats, so I'll talk to her about it directly on Monday. Thank you so much for the information!
