TMI TMI Discharge Pic

Please help.

What is this discharge? I had sex with lube and he came in me, I have the IUD.

I saw this last night but just assumed the lube, however there’s a lot more today. I don’t think it is cum because it has no smell.

My vagina doesn’t feel itchy, but it did burn while having sex. Sex usually is painful for me though.

I’m seeing my OBGYN on the 29, but that’s still a ways out
