I just had a baby 3 monhs ago I've been having unproected sex since then now I've been bleeding a llittle bit after sex light pink can I be pregnant again?

And why not? 3 month old baby and no protection? What would make you think you wouldn't get pregnant?

Of course, you can, no protection, you were trying for another baby

Did you at least wait the time your doctor suggested to allow for the healing of your vaginal canal and any tearing on our about your perineum? If you haven't then you could be reopening and reopening wounds from your delivery.

Sex = pregnancy. Yes, you could be pregnant.

Why would you want to get pregnant again so soon?
