Am I just to worried?

I went to the doc with spotting and pelvic pressure. They checked the hb and to see if I was comtracting then sent me home and said I was fine. And said its normal to feel pressure when pregnant? Now im cramping. I dont want to go back bc I feel like they think im just trying to get an us or something and theyll wave me off again.

But the app said this is all signs of preterm labor. Ughhh
