Ladies who have given birth before!

Any of you ladies who already have kids have pets? Did they react differently/oddly right before you gave birth? My cat has wanted NOTHING to do with me since February, and suddenly the last two days anywhere I go, she goes! And she slept in bed with me last night and this afternoon when I came to lay down from Braxton Hicks, she came and laid on my lap. I don't remember if she acted like this when I was pregnant with my daughter or not! I'm hoping she doesn't know something that I don't haha!
