Probably do a Cat-Scan or UltraSound to see if anything is wrong ! My wife had this same problem for about a week or so afterwards and they had her come in and checked her out . Hers was just a Cyst and said the pain was just a result of the biopsy . He let her go home and it stopped bothering her ! I would suggest that you contact that Doctor and get re-examined for your own peace of mind ! Hopefully it's just from the Biopsy in a very sensitive area !
