Weird CM

Belinda • 23, have a 2 year old son and currently TTC baby #2
Ok, I'll try my best to explain this, sorry if there's already a post similar or something, I did have a real quick look.
​I'm 5-6dpo, well going by my bodys signs, this was the first month TTC so wasn't going to bother with OPKs and temps until next month if my period came. Yesterday and today I've had really weird CM, it's REALLY stringy kinda like EWCM but there's a tinge of yellow to it (def not an infection, I've had enough in previous years to know and there's no smell). But it's thicker than the fertile EWCM I get before ovulation and when I test it with my fingers, it loses it's stringy ness and barely stretches like normal EWCM does. It's actually a lot like mucus plug you lose during pregnancy
​Has anyone else had this? I'm going to test on Sunday, few days before my perio is due and I'll be about 12dpo. Might be too early but guess I'll see! I'm hoping this weird CM is a pregnancy sign or mucus plug forming, idk I need to stop symptom spotting lol
