Potty training at 33 weeks! Vent!

I have a daughter who is 3 years, 3 months old. Also 33w 5d with little boy. We had planned to get the girl potty trained before baby comes but she's not cooperating! I keep trying over and over using different methods but she's just not getting it. Today I cried for about two hours out of frustration and exhaustion! I am thinking she's just not ready yet but I can't be sure how pushy I should get with her..... If I wasn't 36 years old and super preggo I'm sure this wouldn't bed so hard. Anyone have experience and/or advice???? It's a rough one today  😖😖😖
