Pregnant Dalmation Molly?

Hi there ! I am new the board I come seeking help. I bought a few mollys about a month ago. One dalmatian Molly and a black molly. The black molly gave birth the day after I got her home. I had no clue she was pregnant and I don't remember what she looked like as I only had her for a few hours before she gave birth and sadly she died a week later and I have no clue why I was able to save 17 of her babies but 7 have died for unknown reasons as well but the other 10 have been going strong I lost the first 7 within the first week so I think these 10 are going to make it. But now the dalmatian molly I got the same day has been gradually getting bigger and bigger since the day I got her and I just have this feeling it could be any day now but I wanted some advice on whether she needs to go into the trap soon or if its gonna still be a while. I keep saying any day now and nothing happens. She is mostly white with a few black spots so I can't tell if she has the spots around her anus. I will attach 2 pictures so maybe you guys can help me out Sorry about the quality of the pics my cell phone doesn't take great pictures of fish tanks.
