I started a new pack Thursday of last week, and had unprotected sex Sunday night before taking my pill for that night (I take it at 10:30 pm). I then forgot to take Sunday's pill and woke up Monday morning and took it, I also took plan b Monday evening and Monday's pill at the regular time. The pill I missed Sunday was the first I've missed in at least 4-5 months and I haven't missed any others of this pack. What are the chances of me getting pregnant?
