advise?

I'm not looking for a diagnosis obviously, but I've always seemed to have irregular periods but this time its been straight since Feb 23rd. and it's been so much more heavier than normal, the clots are huge and I get intense back pains..i cant see a doctor right now, I just started working yesterday and wont get paid for 2 weeks. I guess I'm just asking for advise from other women who do have long lasting heavy periods..does certain kind of food help? I've been using tampons and pads like crazy. anything to help the pain? any advise until I'm able to get checked out 😪 thanks in advance ladies.
