Bright red spotting

Becca • I`m 30 and married with 2 little girls❤️
Hey all, I recently just got three faint positives over the last two days. However Last night, I experienced bright red spotting before bed. It was about the size of a quarter or two in total. I have been having small twinges that almost feel like the beginning of a cramp but doesn't escalate past that. Not painful. I have not had anymore spotting or blood since last night. 
I keep reading that bright red spotting could indicate a miscarriage? Has anyone had experience with that and not had one? I'm hoping to not miscarry but I am so worried :(
