Very Pregnant Woman in Walmart

When I walked into Walmart last night I saw a very pregnant woman (probably 8 or 9 months) walking with her 3 or 4 year old son. The reason why I even noticed her is because I heard a groan and a sharp inhale and turned around. I looked at her as if to ask "Are you alright?" and she gave me the "why are you staring at me haven't you ever seen a pregnant woman?" glare. So I left her alone and went on my merry way, but throughout my whole shopping experience I kept wondering if she was having Braxton-Hicks contractions or if she was in early labor. And I fantasized about her going into labor and me taking her to the hospital. I so want to do this thing, to help pregnant women, that my mind goes on all sorts of fantasies. I imagined timing her contractions and helping her breathe, making her comfortable, and comforting her son, calling her spouse or loved one, and being the hero. I think I was meant to do this, otherwise I'd leave these poor random pregnant women I run into alone.
