So I'm 5 weeks PP and the hospital told me to start my birth control on the 1st so I did and I stopped bleeding when I started it. I went to my doctors for my pp check and she told me to stop taking it and put me on a different birth control and told me to start it when my baby is 6 weeks. The next day after i stopped I started spotting again. today I woke up and there's a lot of bright blood , could this be my period starting?
