Not here to discredit anyone but I would disagree with the answer that the discharge could not only be present in the morning. Over the last year I battled with a multi drug resistant strain of Mycoplasma Genitalium and I would have a single drop of white/yellow discharge in the morning EVERY SINGLE MORNING, and ONLY in the morning. I think everyone may develop symptoms slightly different but it’s definitely possible.
I had many other symptoms to include itching, burning urination, swollen tip, frequent urination. I took a myriad of antibiotics too; doxy Azithromycin, Moxifloxacin, none of it worked.
I eventually ended up taking 3 months of minocycline along with some supplements and herbal tinctures that I think really helped. I have been off of antibiotics for 4 months now and have tested negative multiple times.
Any STD discharge would not occur just in the morning, and I feel like we covered that last week?
If you are concerned that you have an STD, just go get checked. It's been 12 days since you had the unprotected oral, and you can test now.
