why won't my fish give birth?

Thank you everybody fot the advice! I used warmer water when I changed the water last night and I woke up this morning to little abby fish in my tank! I spent the first 400 minutes of my day scooping them up with a net. I have saved 18 so far from being eaten and hopefully I will be able to save more when I get home! :D

I'd love to hear from you in 6 months to get your feeling towards Mollies! ;)
 
edit: 40 minutes

i saved 22 fry and if there were anymore then they got eaten. I have more than enough and have found homes for them!
