Is this the start of a line or am I crazy??

A little backstory... I got my period 2 weeks ago Friday. But it was light and only for 2 days as opposed to my normal 5 day period. My boobs usually are very sore around my period and this cycle, nothing no pain at all. But I assumed with my period I was out. Every day of these last 2 weeks I’ve felt nauseous. Not throwing up but nauseous here and there. And no matter how much sleep I get I’m dead tired all day. Today I took a pregnancy test as the same time as my opk when I got home from work. In person there is a partial 2nd pink line. It doesn’t photograph well so here is an tweeted pic. What could cause this type of line? Could it just be really really slow hcg rise??
