I’ve been on a different birth control for the past four months. I recently just got my period last Wednesday and it lasted about 4 days. I’m pretty consistent with taking it except one days after getting off my cycle I forgot to take the pill so the next day I took two. The day after I had very light bleeding and I’m wondering if it may have been implantation bleeding. I have been feeling quite off the past two days and a bit nauseous and my appetite is super low than usual. Could I be pregnant?
