So yesterday I was 5 hours late on taking the pill. I usually am on time. Never missed a day.  But yesterday I was late. I took it as soon as I remembered but me and my SO had sex yesterday. (not complaining if we get pregnant) my period is in a week or so and glow said yesterday was my highest day of fertility. I'm on my 4th pack of the BC. Started in October. Is there any possibility???
