I'm taking tri-nessa and I usually am really good about taking it. Well, Friday and Saturday I forgot to take it, but took them on Sunday when I remembered. I usually take them around 9pm at night. I had unprotected sex Sunday night, and he pulled out. I took my Sunday night's pill this morning, so tonight I will be back on track! Should I take plan B? Or am I okay? I have taken birth control over a year

Any time you have sex, protected or not, you risk pregnancy. Miss two pills - and pull out is meaningless and dangerous - and you have a higher risk. The length of time you've taken it doesn't matter - it's not cumulative. You need to take it as prescribed.

You have 72 hours after sex to take Plan B.

And, no, you're not back on track. You need to use another birth control method until you have your period and take the pills as directed.

Agreed, you are in a danger area for pregnancy, you need to start a new month of pills.
