5 weeks and spotting/cramps

So I’m five weeks today! But last week I had cramps that felt like pre period. It was accompanied by some dark/old blood, and I just wore a panty liner and it was fine. So today I don’t really have cramps, it might be a little uncomfortable but nothing extreme and it doesn’t really feel like period cramps. But I do have more fresh/red blood. Again, it’s barely enough to need a panty liner. If anything there’s just more on toilet paper when I wipe. This is my first pregnancy, I’m in between providers due to insurance stuff but I’m just trying not to stress unnecessarily. I’ve read on it being normal for dark blood and some cramps, but I’m having more red spotting today.. is this something I should go to the Er for? I really just don’t want to go for nothing and for it to just be a normal thing. Just trying to get a little peace of mind! Thanks in advance!
