Ovulation test

Today is day 15 of my cycle so I should be ovulating, I had really weird cramps yesterday I’ve never had anything like them so I figured it was bc I just went off my pill at the end of September, we had unprotected sex on October 27 but it was like day 4 of my period so I figured there wasn’t a high risk of getting pregnant (but is so that’s fine with me ☺️) anyways I took and ovulation test and the line was there but super faint... shouldn’t it be bold? Could I maybe be pregnant?
