Spotting at 26 weeks

I’m 26+1 today, and I am spotting. I haven’t had sex in weeks, or done anything strenuous that I can recall over the last few days. But this morning, I woke up with a lot of watery white discharge in my underwear, but wasn’t really concerned, until now, when I wipe and see that it’s a got blood in it, and feeling like I’m feeling “lightening crotch” constantly in my cervix, and have been having mild period like cramps for a week. I don’t recall having this during any of my other pregnancies, and wondering if I should be concerned.
