quoting KMG here:
it seems karna was conceived full term and normal delivery 😊:
The Mahabharata, Book 3: Vana Parva: Pativrata-mahatmya Parva: Section CCCVI:
Vaisampayana said, "It was, O lord of earth, on the first day of the lighted fortnight during the tenth
month of the year that Pritha conceived a son like the lord himself of the stars in the firmament. And that damsel of excellent hips from fear of her friends, concealed her conception, so that no one knew her condition. And as the damsel lived entirely in the apartments assigned to the maidens and carefully concealed her condition, no one except her nurse knew the truth.
also she does call upon surya and others gods for protecting the child:
Do thou listen to the words Kunti weepingly uttered, while consigning the box to the waters of the river Aswa, 'O child, may good betide thee at the hands of all that inhabit the land, the water, the sky, and the celestial regions. May all thy paths be auspicious! May no one obstruct thy way!
And, O son, may all that come across thee have their hearts divested of hostility towards thee: And may that lord of waters, Varuna. protect thee in water! And may the deity that rangeth the skies completely protect thee in the sky. And may, O son, that best of those that impart heat, viz., Surya, thy father, and from whom I have obtained thee as ordained by Destiny, protect thee everywhere! And may the Adityas and the Vasus, the Rudras and the Sadhyas, the Viswadevas and the Maruts, and the cardinal points with the great Indra and the regents presiding over them, and, indeed, all the celestials, protect thee in every place! Even in foreign lands I shall be able to recognise thee by this mail of thine! Surely, thy sire, O son, the divine Surya possessed of the wealth of splendour, is blessed, for he will with his celestial sight behold thee going down the current!
but its his ear-rings and armour which keeps him alive:
Meanwhile, the basket floated from the river Aswa to the river Charmanwati, and from the Charmanwati it passed to the Yamuna, and so on to the Ganga. And carried by the waves of the Ganga, the child contained in the basket came to the city of Champa ruled by a person of the Suta tribe. Indeed, the excellent coat of mail and those ear-rings made of Amrita that were born with his body, as also the ordinance of Destiny, kept the child alive."
Kunti also knows about karna's whereabouts long before her marriage . seems she kept track of the basket as to who found it:
And Pritha (kunti) learnt through spies that her own son clad in celestial mail was growing up amongst the Angas as the eldest son of a charioteer (Adhiratha).
