I agree with laci...you can test 14 days after intercourse.
You may want to see your health care provider regarding emergency contraception (plan b) and possibly also about using another form of birth control...one you don't have to remember to take (Depo Provera shots, IUD, Norplant).
I also strongly urge you to use condoms. Condoms not only help prevent unplanned pregnancy, they help protect against sexually transmitted diseases. Your partner can have an STD and not even know it. STDs can cause long term pain, disability, infertility and even death. You owe it to yourself to protect yourself. You are WORTH protecting.
It is very possible for you to become pregnant with missing two pills in a row. The best time to take a test is at least two weeks after you and your boyfriend had intercourse! Also, missing a lot of pills can also lower the effectiveness of the birth control. If you don't want to become pregnant then I would say try your hardest to remember to take every pill on time! Good luck and I hope the results turn out in your favor!
Yes it is possible to get pregnat if you missed two consecutive pills. How likely dpends on the start of your last period and when you would be ovulating. I would not stress it. However, if you want to test you can get accurate results 7-10days before your next period. Good Luck!
