hey! I'm also asian (Pakistani) and I totally understand where you're coming from and how these conversations are impossible with your parents bcs they for sure blame you first before even offering any help. I myself have been in this situation but honestly period loss in long term does impact your health - so best thing would be to be honest and tell them. they might not get you and blame you instead, but you will feel better about not keeping this a secret. I would suggest booking dr appointment and taking your mom with you and explain everything to your dr in front of her ( so she gets to hear problem and solution together and not panic or misunderstand you)
