The pregnancy themes are important because they are a subversion of a traditional Christian theme, the immaculate conception, as are Bloodborne's version of communion and transubstanstiation.
Queen Yharnam is the vessel through which an Old One, my guess is Odeon, "conceived" a child. Though she lost this child, Mergo, since it is part Old God it exists somewhere out there between worlds, in ghastly form, between life and death.
This leads to two important bits:
1) Now that Yharnam has been "blessed" with divine child, she is the conduit for the Old Ones and her blood is changed. She is made immortal, and anyone who communes with her blood is granted its healing properties.
2) Clerics try to replicate this by providing their own holy blood, in the image of Yharnam herself. Furthermore, The Vileblood Queen is a crude imitation of Yharnam the Vilebloods use as their own conduit of blood healing.
To revisit Mergo, hes basically nightmare Jesus. He cant live in the real world, because he already died and is part nightmare, but he is still looked after by the Wet Nurse because hes Old One royalty.
I think he is Odeon's because Odeon is formless sans his voice and influence, and all we know of Mergo are his cries. I reckon we hear him because thats the only way we can perceive him.
So then the question: is Odeon using the Moon as his physical form? This would make sense given Mergos chamber is the Lunarium.
