I am on birth control and currently taking antibiotics for a throat infection I have. My doctor did tell me that it can counteract my birth control so just to be careful. I had sex on Jan 1st (no condom) and he pulled out. (Its now saturday, 5 days later) I am now on my sugar pill of my birth control. I started the sugar pill 4 days ago. Every time I start the sugar pill I get my period 2 or 3 days after starting it and I still haven't gotten it on the 4th day. Could that be from my antibiotics or should I be worried about being pregnant? If I do need to worry about pregnancy, would plan be work 5 days after sex??

Hi Queencat,

You can take Plan B up to five days after an incident, although it's more effective the sooner it is taken. Do you know how to access it if you wish to take it?

Can I ask if you were comfortable with not using a condom for this encounter?
