I'm looking for a fic where sess asks kagome to bear his heir in change for saving her from some poison. He takes her to where tashio took izayoi when she was suppose to give birth to yasha there. Rin doesn't like that kagome is getting all the attention from sessions and is running of to sess's mom behind some barrier on the edge of the estate. Um oh kagome losses the baby running after rin. That's really all I remember. Please help.

I believe this is Unexpected Endeavors by ella fae. Rated MA, so no YIMs!

An unexpected request rocks the shard hunting group when Kagome, mistakenly, agrees to the deal. Now the group must not only deal with the end of their quest but a moody Kagome, an irritated Taiyoukai, and a very jealous half-demon.

Oh my god thank you!!!! Karma for you.

Now that I'm reading it I don't think this is it.

I skimmed through this story and if you read chapters 20-23 it does sound like the story you described. If it's not is there possibly any more info you can remember about the one you are looking for?
