Need some help please!

So this is my first month TTC, I didn’t think anything would happen with it only being the first month but af is now 3 days late and I’ve had no signs that it’s coming (I always pms pretty bad a day or two before af comes). This evening I felt a little wet down there but when I wiped I just got some cm. I used a tampon to see if there was any blood inside and this is the result. Do you think it’s just af coming late? I hadn’t gotten ovulation sticks yet since we didn’t think it would happen this quick so I’m not quite sure when that happened but this seems too late and wrong color to be implantation bleeding right?? Any thoughts would be appreciated, thank you!
