Implanon to pill

Tina
So on the first I had my implanon taken out because of too much bleeding and side effects were killing me
Now I'm taking a low estrogen pill and I've been on it for a week and a half I'm sure this is dumb to ask but my boyfriend and i haven't used protection besides my birth control is there a chance k could get pregnant even though I haven't not been on bc please help I'm not sure
