Should I call the doctor back and say let me in!!!!!

Started off and light pink when wiping and it stopped. Got to work, I wiped again and it’s bright blood. Throughout the morning until

Now I am wiping clots and clots are in the toilet. Not huge ones but enough to say holy crap! My back is hurting as well as my cramping off and on. I have called the ob twice and each time she says is it filling up a pad within an hour? I say no because I pee every 30 minutes!!! When I pee I have a reddish tint and I wipe and of course there is blood and clots. I am so confused and lost! Do I call her back for the third time? Do I let it go since it’s not a constant pain? I just need guidance please😩
