Is it possible

Is it possible to be pregnant on birth control? I had some spotting in the first day during my placebo pills (usually when my cycle starts) and nothing since then. I have breast tenderness, frequently urinating, tiredness, slight nausea, back pain and cramping. Now I am aware that these symptoms can be a number of things but I was just wondering how many people gotten Pregnant while on birth control.

Oh and I took about ten test and three had faints lines and the rest nothing at all. I’m so confused.

And before y’all all say hi to the doctor I already made an appointment. I just wanted to see if others had experienced it.
