What are the complications of a biopsy?
1) bleeding for a couple of days.
2) cervical stenosis that may lead to dystocia (obstructed labor) if your pregnant or to secondary infertility only if done excessively or using wrong technique.
3) cervical incontinence that may lead to habitual abortion.
But these complications are rare and you can discuss with your doctor if you want to get pregnant and have kids in the future
