I was on birth control for a month then in the middle of my last pack I left it on the sink while I was on vacation so I missed 4-5 days of it. I have been bleeding lightly for 10+ days. I started a new type of pill 5 days of not having my pack and my boyfriend came in me a few times. What are my chances of being pregnant? I can support the child that is no problem I am just wondering if I should be worried or not. I am feeling very hungry and tired, and Nauseas. I just don't know if it's possible to be pregnant while breakthrough bleeding.
