No, I'm not using any BC. We only use condoms for protection when we're do it. The bleeding stopped and has turned somewhat normal now. I bought some HPTs, just in case and the first test came out negative. I'm planning to re-test again next week and see what the future holds for me. And I thank you for your response to this. :) I would try to get to a doctor since I'm already having problems with painful cramps during the first days of my period.
Are you any type of birth control? If so, that could be why you are bleeding. You are not very likely to get implantation bleeding a week after your period so I doubt it would be that. There is also the possibility of a bacterial infection or something, as they can cause irregular bleeding too. If it continues, I would go see your doctor for a swab.
A very quick answer will be most helpful.
