Monther's intuition

I work with my mom often. We are in the real estate business and she is my Broker. So today she came by to pick me up to meet with a contractor. As soon as I got in the car she randomly said she thinks Im pregnant. I haven't spoken about TTC or mention anything that might tip off a symptom. I asked why she thought this and her response was she had just been feeling it for about 3 or 4 weeks now. Ironically AF is due tomorrow. Very curious to test tomorrow just to see if her "feelings" are accurate.
