Should I go to the ER

I’m 6w + 1 pregnant and 2 days ago, I experienced dizziness, to the point I was incredibly light headed and almost passed out. (I’ve had bad food aversions and forget to eat just generally so I thought this could be the reason why) Last night, I had light brown spotting, just when I wiped, and had mild to moderate cramping all day. Today, there’s no more spotting and I haven’t felt dizzy since I’ve been making sure I’m eating enough, but I’m having more intense one sided cramping (the right side, which is also the side I ovulated from and implanted on) and the spotting last night really freaked me out. I’m starting to worry. Is an er visit warranted? Keep in mind I know there’s nothing they can do if I’m miscarrying but I’m also concerned this might be ectopic. Am I over thinking this? Is an er visit warranted?
