Be sure to check with the park or organization before you go. Like I saif, many won't allow pregnant women through. It's a liability for them.
I was asking that. I'm 34 weeks and I was planning to on holloween when I would be maybe 38w and they told me to make sure someone was by my side
Im 25 weeks and love haunted houses, i asked my doc she said it was fine to go just not to fall or cause trauma to my belly (obvious stuff). Ask your doc though.
I don't think that it would be such a good idea when pregnant. Last year a guy with a chainsaw ran after me while I was in a haunted corn maze. I couldn't imagine me running while pregnant XD
