Feel a bit silly having to ask this. So I’m currently 20 weeks pregnant and I was just wondering about the effects of fireworks on the fetus inside. I was walking around outside for about half an hour when the firework had started to go off around the area I live in. I’m worried that the exposure to the fireworks, with the loud sounds and bad smells, may have affected my unborn baby. They appear to be moving as normal but I’m really paranoid. Can anyone give me reassurance?
