Yes, I did. Infact I was consistently (almost on a weekly to bi-weekly and then monthly basis till delivery) going to the temple at havelock road and pray to zsnn for smooth pregnancy and protection especially I had bleeding in my 1st trimester and carrying twins. Most of the time I only bring flowers. Either those in stalks or packet kind. Packet kind after praying for her blessing I'll go hm and shower with it. Importantly, go with a sincere heart. Even now that I've delivered, I still go there pray on a monthly to bi-monthly basis. Oh, and I was told pregnant ladies are not supposed to kneel to the gods. I just followed anyway. And yes, once you delivered and bb full month, return red eggs.
