Are pregnant ladies allowed to visit columbarium? Qing Ming festival soon

My MIL and hubby didn’t allow me to go to the columbarium at all. And I also didn’t attend my baby niece’s funeral when she passed at 12 days old. Family members will be understanding of our situation as they know that pregnant women have a lot of pantang. As hubby and I have been trying for 4 years and this is our first pregnancy, also that we’re having twins, I just listen to all the don’ts that my elders tell me. Better to be safe than sorry.
