I've noticed that a lot of oviposition related images have the pregnant tag.

Pregnancy only occurs when an egg is fertilized, and unless there's additional context in the image, there's no way to know whether or not an egg is fertilized, especially in the context of tentacles and other vaginal insertions.

Some notable examples:

has the pregnancy tag, despite no fertilized egg being present, no pregnancy context being present, and literally just a slime filling the womb. Not really pregnant, doesn't look like she's giving birth either.

Easter eggs, especially in context, are usually made with unfertilized farm eggs, and putting eggs inside oneself does not constitute a pregnancy.

Pregnancy implications with eggs should be limited to species that can actually lay eggs unless additional context is provided.

I believe there should be a difference between laying eggs (regardless of them being fertilized or not) and inserting eggs into... holes.
Maybe keep oviposition for the former and egg_play or egg_insertion for the latter.

But then you have the problem of characters laying eggs of their own and using them for "playing".

And then there's the chaos that is Yoshi.

Right now we have the underused eggnant tag, which implies a character to be "pregnant" with eggs. Normally the term used for this is "gravid", but that's already been aliased away to pregnant. I feel if there is a large belly and there's no other context of insertion, and the character is laying eggs, eggnant should be a valid tag.
Unfortunately for this dilemma, eggnant implicates pregnant. There was an attempt to alias it to pregnant, to stay consistent with the gravid alias, but the admins decided it would work better as an implication.

If we do that I think there should be a tag that all egg fetish-related tags imply, because boy are they a mess right now lol. Sometimes you want to find[or blacklist] anything related to egg fetishes, but egg is too vague [pulls up images with eggs in the picture but no actual egg laying or insertion is depicted] and oviposition or related tags are too specific and commonly under- or mis-tagged.

The second half of your post is pretty "spot on" with my issue. If I search for pregnancy, often simple egg play stuff comes up.

Lots of images where tentacles are laying eggs inside someone just because it's a fetish have the pregnant tag, despite eggs not being fertilized. Eggs that are fertilized but not by the host also aren't counted as a pregnancy in bioscience communities, an example being wasps which lay their eggs in the flesh of other animals so the hatchlings have food when they hatch. A good example of this is in Michael Crichton's "Micro" novel, if you've read it.
