Stranger knows I'm expecting before me???

Hello everyone. To start my story I'm not trying to conceive and I work at an airport. I have always had bizarre cravings but eventually they subside but not in the past few weeks. I usually eat maybe once a day now I eat at least 3 times. Also I hate apple juice but I have been wanting it. Also I have not even thought I was pregnant until recently. My friends have been joking about me being pregnant as do I to them. Long story short I work at the ATL airport so I encounter a lot of people. I was pushing this elder Latina lady to her gate and when we got there, she got out of the chair, turn around, grabbed my stomach, said some stuff in Spanish and smiled. I didn't know what she said or why she was touching me so I just smiled back. But it stuck with me. I don't know if I am but last night (happened that evening) I made my appt for tomorrow morning. Have any of you ever had something like this happen to you and it was actually accurate?
