Potty training.

Help! She's 29 months & isn't potty trained yet. We have tired several times before. Big girl underwear, rewards, toys etc. I feel like I don't do it enough. She says pee pee momma & I try to take her as soon as I can but she is normally done peed so idk. Anyone have any tips? Plus I'm 30 weeks pregnant and don't want to stres too much because last time I did.
