Concerned

So I’m 4 weeks and 6 days pregnant and when I went to the bathroom and I wiped there was snotty looking discharge. I’m not burning, itching, foul smelling, or anything funky going on. What could this be? I have one son already and I remember at 3 weeks I passed a big gob of snot and it seemed to have been normal cause nothing ever happened. Just wandering if this could be the same thing or what?
