Friend moving in

Alright I need advice. I’m 20 weeks pregnant with my first. I live in a small 2 bedroom apartment with my husband and 2 dogs. My friend is having major relationship issues. She lives 4 hours away from me but I offered her to move in with me because she made it seem like it was terrible. I was prepared to go get her and her daughter right then and there. However she told me she wasn’t sure. Totally understand. I didn’t hear from her for a week so I started to think she didn’t want to and so I started to plan my nursery again. I got a text from her today saying she wanted to sometime next month.. Is it bad I almost regret saying anything? I was so looking forward to having a nursery and preparing everything😕 I just thought if it was as bad as she said she would have wanted to come sooner and talk to me more about it. I don’t really know what to do or feel and the hormones aren’t helping. Advice please
