Not sure what to do... Any advice pt 1

Hey ladies. I have a 2 1/2 year old daughter. She used to sleep through the nights in her own bed in her own room. Now that im pregnant she wont sleep through the nights. She crys sometimes 2 or 3 times a night. If im lucky just once. My hubby dont get up because he goes to work at 4 in the morning. And she only crys for me. She has the same sleep schedule that she has always had. Bath, snack, read the same 4 books, pray and bed. She falls asleep before im done reading all her books.she sleeps with her teddy bears and baby dolls...

I dont know what to do anymore im in my 3rd trimester im so tired and frustrated becuase she wont sleep.
