Need some advice

So I have 10 days before AF is due, 5 dpo and today late afternoon I bled and have the slightest cramps but it wasn’t much I put a cup in just to be sure just incase I was starting super early but hrs later I took it out and there was just a tiny bit of red/brown colored discharge on it but not filling it. I whipped and it looked like this…. You can’t tell by the picture but it is like stretchy gooey like I’m not sure I have never experienced this…. Any ideas would be very great full
