I had my period almost a month ago, I started birth control pills right after (only took 4-5) & missed a dose (didn’t like the way it made me feel so I quit taking it) which then gave me another period.

Now I’m unsure if my body is coming off of the birth control and making me feel pregnancy symptoms or if it’s possible I am pregnant? Personally I see a faint line on these tests, and so does my friend but when I took a walgreen brand test, it was negative:/
