I've been on Microgestin 1/20 for around 3 months now, and I finished my last period on last Saturday (6-8-14) and I had unprotected sex with my boyfriend on Sunday (the first day of my new BC pack). Is there any possibility that I could be pregnant?
The only time there is a need for back up is the first seven days of the first pack as long as you take your pills correctly with no misses. If you were to miss a pill, you'd need back up again for seven days following the miss. You were not unprotected, you were protected by the Pill when you had sex-once you are protected it is 24/7 as long as you take them correctly! (but I know what you meant). Pregnancy is still possible while on the Pill-no contraceptive is 100% effective but the Pill is 99.9% effective when taken perfectly, every day and on time. Slight deviations, taking it late or missing an occasional pill can decrease the effectiveness slightly to 92-96% effective depending on how much of a deviation there is so it is in your best interest to try to take your pill every day as close to the same time of day as you can!
