MY SISTER IS NOT LIVING WITH ME ANYMORE!!! AND SHE IS TRYING TO GET PREGNET. WHAT SHOULD I DO???
First up you need to tell us how old your sister is. If she is below the consented age and plus 2 years over the consented age, maybe she needs to rethink it. However if she is old enough and mature enough, there is nothing you can really do about it. Just let her know that you will support her but you won't be the one left holding the baby, she will as a duty as a mother.
How old is your sister?If she like 17 and older let her go.she need her own life now.
but if she like younger like 16 or 15 talk to her.
Apologize from here and tell her to retune back.
