I've been on birth control for almost a year now. Combined monophasic pills (Marlissa).
I had unprotected sex on Sep 15th, 5 days ago. He ejaculated in me.
I am on birth control and I try to be adamant about taking my pills correctly. I have never missed a pill, the latest I've taken a pill in the last month was by a couple minutes. Every pill from this pack was on time.
I found today that I am having slight bleeding. I am aware that bleeding is not a sign of pregnancy, but I was also informed about implantation bleeding. I am not sure what to believe. I am feeling quite nervous about it and was hoping to recieve a clear answer. I have 9 pills until my first sugar pill. My last period was normal.

Thank you
