Critical Issue

A Christian sister in a certain Church got pregnant, the Church decided to discipline her since she was not married.

When the elders of the Church met her, she told them that she has stayed in the Church for years and no one is marrying her and she is getting to the age were she can't get pregnant if married.
So she went and did artificial insemination since she wants a child. She provided the medical documents that showed that she has done the artificial insemination.

The Sister is pregnant without committing fornication nor adultery.
Not so?

BUT,
COULD THIS BE A SIN?
If YES or NO

Give your reasons for your answer.

If possible Back it with Scripture, so dat we can learn.

Sin is derogatory term used by primitive and ill-educated minds. IVF has been around for eons of time lines. Even your Jesus was a product of IVF, why call it a sin? I think by saying sin, you mean "evil", " wrong" etc
