I have missed some pills through out the 21 days and last week of the 21 days. then on 7 day break had spotting 2nd and 5th and now nothing? pregnant?

Maybe. Maybe not.: It can be hard to guess whether a woman is pregnant or not. A urine pregnancy test gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a withdrawal period, or after having a "weird" period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test.

Check a pg test.: Check a pg test to be sure, anytime your period is abnormal, in length, symptoms, or timing. Repeat in a week and if negative, and you still have spotting, see your doc to find out why. Follow the instructions on the kit, and be sure it has not expired, too. Also, infections can occur, if you are at risk of pregnancy. So get checked for those if your pg test is negative. Practice safe sex!
