Yes, in a way, Venom did get Eddie Brock "pregnant," resulting in the birth of a new symbiote.
While not a pregnancy in the traditional biological sense, the Venom symbiote essentially reproduced within Eddie Brock, leading to the creation of a new symbiote offspring. As seen in the provided video excerpt, Eddie Brock experienced symptoms, complete with disturbing visions, ultimately leading to the birth of the Sleeper symbiote. This event is considered a significant and chaotic occurrence within the Venom storyline. The birth of the Sleeper symbiote from within Eddie Brock can be interpreted as a form of "pregnancy" since it involved the creation and emergence of new life from within a host. The process included a period of symptoms and changes within Eddie, further supporting this analogy.
