I am a Sunday starter on yasmin.I usually take my pills religiously but after the last pill of my pack I was out of town and did not have a new pack with me so I ended up starting a week late which means I was off the pill that whole wk. During that wk I had one act of unprotected sex(which means it was the 7th day after my LMP).now I'm worried because my breasts r sore but I'm wondering if it is because my cycle and body r off because of the late start or could I be pregnant? I have not missed my period yet but I am soo worried pls help.
