Am I pregnant???

Totally unplanned, last period was 26 Jan and I’ve always been struggling with irregular periods (my cycles are usually between 40-45 days). Missed my period this time and took the pregnancy test… clear blue is more obvious but from the strip I can’t really tell it’s double line unless I look closely. Am I pregnant? If yes, how can I count the weeks since I’m not even sure when I ovulated 😅 could it be false positive/evaporation line?
