Ladies I really need advice ...nobody else to ask

So I have been feeling off the past couple weeks. All pregnancy symptoms. I have been pregnant twice so I just recognize it.

So there’s the thing ..I am on birth control but I missed it a few hours a couple weeks ago. I was taking pregnancy test this week and saw a faint line. Now I have my withdrawal bleed for my pill.. but still feel off. Is this possible ? Could I still have a chance to be prego ?
