4.5 weeks and spotting

Hi there

I am pregnant with my second and am about 4.5 weeks. For the last 24 hours I have been I guess spotting mainly brown rust color when I wipe with a few times seeming a bit more on the red side but not bright. No cramps or anything and I don’t remember this happening with my first so I’m freakin our. I had a liner in and barely had anything on the liner only seems to happen when I wipe but it’s every time I wipe.
