There are a few things you can do. You can leave her in there and let the strongest survive once they are released.
Separate her into her own tank so she doesn't get harassed and fry won't get eaten. (take 21-40 days)
Buy/make a fry saver if no other tanks available.
Catch her at 2.5-3weeks and strip her.
My opinion is to catch her, put her in another tank and let nature do it's thing. If she swallows which is normal for the first time then she will eventually learn how o hold them full term.
That is what i do.
