I would like to know does it necessary to purchase a maternity bra? Can i just wear the normal bra that i am wearing now?

If you still feel comfy in your bras. Mine start swelling in first trimester and it started to get uncomfortable in my underwire bras so I got a few nursing bras (padded no wire). Suggest to get nursing bras instead of maternity which are so comfy to wear and can use for nursing. I bought autumnz nursing bras at the baby fair and the staff measured and recommended the sizes for me based on rough estimation so could still fit nicely for nursing later on.
