Honestly I thought it was an interesting question and wished you would enlighten us more about the "standard lore"
A quick google search brought up this;
" In Balkans folklore, dhampirs (sometimes spelled dhampyres, dhamphirs, or dhampyrs) are creatures that are the result of a union between a
vampire and a human. This union was usually between male
vampires and female humans, with stories of female
vampires mating with male humans being rare. "
From another perspective, I ran into a

which mentions the following (from the elder scrolls lore;
"Lord Lovidicus sired a child as a vampire, which suggests that all of his reroductive organs were functioning correctly. While it's possible that a woman's womb would react differently to the disease (on earth there are disease factors that can damage a woman's ability to bear children but not a man's), I don't think its outside the realm of possibility
The main thing that I think counts against it is whether or not the embryo would then to be a vampire. If Vampirism is a species, then by Racial Phylogeny, the child would be a vampire since its mother is a vampire. More likely since we know that Vampirism is a disease, it would be passed on to the embryo. However, we know that vampires don't age or grow (Babette in Skyrim), so would a vampiric embryo be able to grow into a viable child? In my opinion it would not, and the vampire would miscarry.
If the child does not contract the disease in-utero for some reason, then the child would need a constant supply of nutrients from the mother, meaning the mother would probably have to eat something other than blood (since blood provides more of a magic sustenance than a physical one). Then the child would be born as not a vampire and can carry on its mortal life. Or, if it contracted Vampirism immediately after being born for some reason, you have an eternal and immortal newborn which is not a great prospect for anyone.
Edit: I have retracted the assertion that the mother and embryo share a circulatory system. Rather, they share nutrients across the placenta, which also can act to block certain diseases. Whether this would allow the child to remain Vampirism free is up for debate."
There is some food for thought.

Question:
Lets say both of a person's parents are vampires... would the two create a vampire offspring?
Answer:
There is some disagreement among vampire mythologies about this, but the consensus is that vampires cannot reproduce as they did when they were human. So the answer would be "no".
But here's why: Vampires are technically dead. Their bodies don't function the same as they did when they were alive, which is why they don't generate body heat and why they can't digest regular food (they absorb blood, they don't digest it). Therefore, it is reasonable to believe that this is the reason they also cannot create a child via the regular sperm/egg method. This also, though, explains why a vampire bite can turn others into a vampire.
Every species on earth has learned how to reproduce. There are even some cases of amphibious creatures literally changing sexes in order to keep the species alive. There's no doubt that vampires developed their

for this same purpose.
In other words, vampires reproduce through the transfer of this bacteria, most commonly through a bite. If you think about it, this is much faster and easier than a 9-month gestation period and only takes one "living" vampire to reproduce.
That said, there is reason to believe that a vampire male may be able to reproduce old-school style with a human female. It would have to be in this combination because only a human female would be able to carry a living fetus. Most animal species, including humans, can continue to produce sperm all the way through life, and even though a vampire is technically dead, there are some still active elements...

Conclusion? Could go either way?
