Pregnancy suspicion after PAP

So

Okay so this may be a strang and long story. Sorry in advance.

I have a 19 month old son. I've been struggling lately so I had this feeling I might have postpartum depression. Well we moved states when my son was 3 months old and I never bothered to look up a doctor because being a mom.is busy and we had career changes and we were couch surfing until we could find a home, etc.

So I finally went to an OB yesterday. I explained that I haven't been interested in things i used to do, i get angry or sad all the time...yadda yadda yadda. We discussed my first pregnancy, my son and she diagnosed me with late, high functioning ppd. We decided no meds but to keep working on myself through exercise and daily awareness. Anywho i mentioned that I was concerned that something may be wrong with me because we have been extremely less than careful and I haven't gotten pregnant yet. Not really "trying" or hoping for anything but definitely not as careful as we've been in the past. I had some postpartum issues and infections that made me think this. And my son was 100% planned and was conceived 2nd month of trying. She said it's probably nothing but she'd check and make sure everything is okay.

So onto the PAP. We had a general conversation so she could keep me relaxed. And then she kept talking about pregnancy. She said, "when you get pregnant next" or "next pregnancy" and even said, "i predict pregnancy will happen within the next 6 months". She talked about how she does her doctor visits with pregnancy, and then she left the room saying, "okay, when you are pregnant give me a call"

I know through text it may not translate well, she was actually really sweet and helpful! But then I got to thinking, I've never experienced this at an OB visit. Like "willing" pregnancy on me. I know I mentioned my spouse and I weren't careful, but it doesn't mean we want to have more children, or what if I have problems or something? So I just thought it was weird because it could have been insensitive to someone else. So, I looked at my calendar. My visit was about 2 weeks after we had unprotected sex...but according to my calendar I wasn't quite ovulating yet (not in my window). But now I am wondering if my app is off and I'm ovulating sooner than predicted and that's why I also haven't accidentally gotten pregnant either. But I haven't missed a period yet, so I can't actually test my theory yet.

So I'm wondering if maybe she somehow could tell that I might be pregnant now, and that was all her "hinting" talk? I read the cervix could be different in early pregnancy, but if the baby hasn't implanted, then my body wouldn't even know, right? I'm just looking to explain her adamantly talking about my getting pregnant since that wasn't really a conversation I've had with an OB before at a checkup. But maybe it is normal after having a kid? Thoughts????
