Implantation bleeding..?

Hey everyone!

I wanted to get some insight. We’ve been trying to conceive for about two years. We’ve made a bunch of lifestyle and health changes to try and increase our chances to get pregnant. I know that not many women get implantation bleeding, but I’m now about 10 DPO, and I had the lightest spot of blood yesterday and a tiny bit more today.

I have PCOS, and I read that I’m supposed to avoid early detection tests because it apparently can read as a false negative. So I want to wait until I’m at least 1 week late for my period. I’m due for my period in about 3-4 days.

What do you guys think?

Yesterday:

This morning (I’m not sure if that’s clotting or not - it looks to me like it’s just blood mixed with cervical mucus):

Thank you so much in advance for your help!
