So ever since I took plan B aug 22 after taking it I had light bleeding then it started to get heavier but I stopped it by taking my bc ( which I was taking my bc kinda regularly before having to take the plan b , wish that I didn’t ) but now I’m having this brown discharge and some light spotting what should I do ? Feels like another period wants to come . 🤦🏾‍♀️ really regret taking the plan b I just wanted to be on safe side since condom slipped off when he came in me .
