Period is late, but she's on the pill. Please Help.?

If she is only a day late then you should not worry at all. But just for the record, you do not have to ejaculate to get her pregnant. Pre-ejaculation comes out while you are "getting busy" and that sometimes works just as well. And if she's that worried, Tell her to get the shot. Also, her stressing about one day, can lead to 2 days, then 3 or 4...Stress can cause you to miss a period all together in a month. I missed 3 months due to stress. Tell her to calm down!!!
