You can buy a belly bumper thing that protects your belly from being hit, and only being 6 weeks, baby is very well protected, but I personally wouldn't risk it.
You shouldn't goto anything that risks you getting hit in the belly. Especially since your at a super fragile part of pregnancy...even though we are fragile the whole time
I went a few years ago ppl run around and act crazy they run into u and stuff I live in orl fl so it's tempting but I decided against it for those reasons plus I don't think there's any safe zones
