Can female vampires get pregnant?

We know that male vampires can indeed maintain enough of an erection to sire children, as seen by the existence of Agronak gro-Malog, but what about female ones?

Surely having no heartbeat would mean they're unable to menstruate, which would mean no eggs available to fertilize. We can probably assume that they still have an intact uterus, but surely there'd be no ovulation happening in there, right?

Are there any actual sources about this topic?
