Not sure what to think

I've recently started birth control, I read the instructions etc did what I was suppose to do and ive recently started feeling differently I took a 2 pregnancy test at two different times and it is super faint but there is a line there, I stopped taking the pill for the time being to determine what is actually going on and plan to start back next month if I'm not pregnant (this will be my second if I am). But what are opinions of the test results? False positive? Wait and take more in a week or two? It's confusing, I've been on BC before and no issues Or mishaps and am always very cautious Taking it same time every day etc.
