Spotting 32-35 weeks

So I’ve been spotting on and off from 32-35 weeks. It has been mostly tan/pink but yesterday I had some red/clear (thought maybe mucus plug). Today it is back to pink/tan. This is my second pregnancy and I never had this with my first. I had testing done Saturday for UTI/bladder infection as well as blood for other issues. I haven’t heard back. Now it’s Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and I’m sure I won’t hear back until Wednesday. Can anyone shed some light on this situation? 😕
