Yes I would, and have done in the past.
Once when i was 7 months pregnant, i passed out at a bus stop (low BP). It was the middle of the day, very busy road in the city centre and about 20-25 people at the bus stop. I collapsed onto the ground, and when I came round was still lying on the ground, lots of people staring, some ignoring me, none came to help. Not one. Includung a woman who was stood right next to me, just staring.
I had to get up and I burst into tears and sat on the pavement to call DP to come and pick me up in the car (he worked just round the corner, thankfully). Even in the 5-10 minutes it took for DP to arrive, i was sat on the pavement, in tears, and still not one person stopped to ask me if i was alright. And i was VERY clearly pregnant!
Disgusting, I think. DP was SO angry he was going to come out of the car and shout at all the people but didn't, thankfully!
It really upset me and made me a bit frightened to go out alone after that, as i was prone to passing out due to the low BP. I basically stayed in unless i had company from then on.
