It's probably not milk but more of a hormonal issue. Milk for most women actually doesn't come in until they've fully given birth (a couple of days after and you have colostrum which you have right away but it is not like milk that flows and engorges your breasts.). So, I'd guess your hormones were in shock with the abrupt change after termination and are still adjusting. If it continues, talk to your doctor about it. Some women have this without ever having been pregnant so it is not necessarily related. How's it going now? It's been a couple of weeks since you posted this.
