Hi, hoping for some advice please. I'm very early pregnancy and I'm booked to do the O2 climb next weekend by which point (fingers crossed) I'll be 8 weeks. Their website just states that it's not suitable for pregnant women but doesn't say why. OH seems to think it will be fine but I'm not so sure. What do people think? Physically I feel fine just a little tired but I did some hill walking this weekend which was fine. I'm not sure if there's a reason they advise against it e.g. is it physically challenging or dangerous or is it the harness itself or is it just for insurance purposes? Has anyone got any experience? No judgement please, its our first time and it was booked before I found out. Many thanks
