Hubby and I have been ttc for a year and six months.  I have PCOS and super irregular periods.  My doctor tried to take a biopsy of my uterine tissue but my anatomy makes it difficult to get anything.  My cervix sits very high and tilts to the back.  So she suggested a laparoscopy to get in there and make sure my tubes are open, my ovaries are okay, there's no cysts or other abnormalities, and to get a good biopsy sample.
