Sorry you needed a cone. Did you have a irregular pap smear? Your doctor can help you but in general, a cone biopsy does not usually prevent someone from getting pregnant. In very rare instances, miscarriage can happen though after the procedure. Once in a blue moon, a woman can have an incompetent cervix after (which a stitch fixes) but it is rare. And even more rare is cervical stenosis which makes the passage way that sperm needs to get through very narrow. Again, really rare. MOST women go on to have healthy pregnancies after cone biopsy! good luck
