Good or Bad Cramping?

I’m 26 days late and have only managed to get faint positives over the last few days. Now I’m experiencing an abdominal cramping/bloating sensation as well as lower back cramps. Also, I noticed some light spotting yesterday but it wasn’t on my underwear, just on the toilet paper. Today, however, the spotting has been a little more frequent but with no cramping until just a bit ago...Now I’m experiencing cramping and light pink spotting. Should I be concerned?
