OPK first month test help

Maddie

Hello.

I’m trying for the first time opk tests, my gyn suggested that i try these. Since my period it’s irregular, I started doing them since 7 days of my period ( 27 January until now 12 february doing sometimes 2 times a day. the results were like the photo below.) I have one which is more colored than the others, i had intercourse that time since I thought it might be the right time. Do you think it was positive or not ? Since that day it was very very unclear 2 lines (I marked with black )
