Help ! Is this shadow a evap line or faint line ?

Yessi

Hi, I do not know how many DPO I am but I had my period 11/28-12/4. My periods are irregular some 28 days cycle others 30 days others 40 days etc

Yesterday I saw a similar shadow but it was lighter. This was taking this morning . HCG test strip

I do want to mention for the past 8-9 days my temp has been 98.4-98.6

My usually temp is high 97s

Can someone help if this is an evap line or possible a faint line ? Planning on getting a brand test this weekend , I can’t buy a ton and waste money 😅

Thank you in advance
