Could this be a first Herpes outbreak? Please help

Hi,

Im currently looking for help as i’ve been unable to get an appointment at walk in clinics for past two days. I thought maybe this could be Molluscum Contagiosum but I cant rule out the possibility of it being Herpes.

Ive been with the same sexual partner for 6 months and she tested negatifve to Herpes 3 months ago.
Prior to that my last sexual relationship was over a year ago. It doesnt make sense that this could be possible but please let me know what you all think.

Here is the three day progression;

Day1

Day2

Day3
