Should I bring it up?

I've noticed my mom doesn't talk to me unless I make the effort. For instance, this week as an experiment...I haven't called or texted her to see if she'd make an effort...I haven't gotten anything. I should also mention I just got into my third trimester and may be over thinking this but when I looked at my call log, all of my calls with her have been me making an outbound call to her. She never makes plans with me unless I make them and I'm just feeling some type of way. When were together with family, since finding out I'm pregnant, she was always saying that shes gonna annoy the crap out of me when checking up on me. I simply laughed and said annoy away. I would screenshot my whole call log with her, but this is just a glimpse. We do have long conversations...maybe I'm overthinking it? Should I bring it up to her? Or leave it be?
