House Training an Adult Dog?

We took in our Pit over a year ago when she was 2/3 years old. She has had accidents and we started the crate training. We are even putting her in our room, however she cries and grunts all night long which is annoying with a toddler next door who is a big time light sleeper. We put her back downstairs and she was fine for a few weeks.

Now she has peed in our son's bed while he was sleeping. Every month or two she tends to pee/poop on our new flooring and everywhere else in the house when unattended.

We take her out a lot, and she usually goes, but at times she will come in on her own and do her business in the house. It happens when anyone is away from her for more then 10 min.

We recently found out that she has been pooping and peeing in the basement. Since we don't go down there a lot I don't know how long it has been there. To top it all off she has a tendency to poop then roll in it.

Yesterday we took her outside, and she did her business and came back in. I found out that she didn't wipe her butt at all and smeared it all over our fabric couch which she usually lays on a lot. This is the first time this has happened.

I'm 4 months pregnant and this is getting too stressful for me. I'm at the end of my rope and I don't know what to do. Please any advice for this will help. I don't want to give her away, but it's getting to that point. I'm worried that when our baby is born she will be worse.
