Daughter is 3, regressed for no reason?

I am pregnant with baby #2, due in Nov so I am even more set on having my DD potty trained. About a month ago, she had used the potty to pee without any accidents (we were still working on #2's) for a month. Wore underwear at daycare and everything. Suddenly she quit going and won't even mention when she wets her pants or anything. We have her in pull-ups but she is content not going and even makes it seem like it's funny she isn't going to the bathroom. We had a reward system in place but even that won't encourage her to go anymore. I wouldn't be pushing it if she hadn't already been accident free for a month so recently. I am just at a loss of what to do. Anyone else with this issue??
