no because "when i was born" expresses the fact while "I was being born" expresses the process

"I was born" is written in the past perfect tense. It means that the process of you being delivered from your mother's womb is complete. Finished. "I was being born" is written in the past progressive tense, and means that the process of you being delivered from your mother's womb started (in the past) and another action occurred during your delivery, hence; while you were being born, your father had his head next to your mom's head. Both sentences mean the same thing, but the latter, written in past progressive allows the writer to include a secondary clause to the sentence, describing some other action taking place at the same time.
