There's always a chance without a condom. There's precum that could get into you. You've only been on the pill for 2 weeks? That's not long enough for it to fully be in your system. Be smart, if you don't want a baby use proper protection.

If u just have started the birth control you need to use other forms of protection that whole month you started thawing the pills. Mainly because it's something new getting into your system and first you don't know how your body will replace to this particular pill and second if your not use to taking a pill everyday then u could miss one and then you could get pregnant ... 

Most pills need one full week of taking it at the same time each day before you are protected. Sounds like you should be okay. Read your information leaflet inside your pill pack and see what it says about when you are fully protected. If you threw that out, Google your pill brand and read about it there.Keeping in mind that the pill must be taken at the same time every day to be 99.9% effective, you still have a .01% chance to get pregnant, but it's very rare. I've been on the pill for over 10 years, sexually active on it for 8, and while I've had 4 pregnancy scares due to stress, (I don't get stressed often and I don't handle it well when I do!) I've never been pregnant on the pill.If you do get nervous, but some pregnancy tests and take them if your period is late or doesn't come one month. It's always comforting to know you have them on hand and won't have to run out to the store to get them!

No need.
