While it is debatable given the references I have found from Sahih Bukhari as to whether the walima requires consummation or not, it is definite I believe that consummation is a sunnah if done and desirable before Walima. It is however not a requirement.
As for the periods thing, I don’t know if you know this, but most Pakistani families actually plan a wedding around the expected monthly date so that a bride isn’t on them during the ceremonies.
Walima is one sunah, walima after consummation is another. One can combine both sunnah if possible but walima is not going to be haram if Sex did not happen
I know about how the dates are picked and that is why Larki walay pick the date, but possibility is always there, right?
Yes it is very much possibe! Happened twice in my family! Wedding was planned according to brides cycle, yet she started her period on the day of the wedding itself in both situations! Awkward!!!
