I have not given birth or been on the receiving end of investigations like this. But you are telling me going through 4-5 more months of carrying the baby to term would do more harm to this young lady than the invesigation process, wondering if you will get caught, getting caught, and then 90 days in jail would be better for her?
That’s her choice to make. Birth is a traumatic event (for all women) carrying a chance of death and long-term damage to their body. It’s not important what you think is easier or what you accept, it’s her body and should be her choice.
