So I’ve been on lolo birth control for a little over a years now and my period has always came. I take the pill at the same time everyday, give or take 10 min, and have never missed a pill. I’m so careful that we use condoms mostly w pulllout or twice this month no condoms but just for a minute and then pull out . Anyways I was supposed to get my period on Sunday ( today’s Wednesday) and I didn’t. Yesterday I put a pad on and from all day, this is all that cake out . Could this be implantation bleeding ? Am I pregnant ?
