Add a comma after cyborg.
Don’t capitalize if, because it’s neither a proper noun nor the first word of a sentence.
Change she may also be pregnant to she may also have been pregnant.
He was a cyborg, and she was a clone. They were also an item, and if that wasn’t enough for society to take in, she may also have been pregnant.
(I’m too tired to type the bloggish tirade that the topic of this example deserves…)
