I had unprotected sex (condom slipped) on January 13. Took Plan B One-Step 3 hours after the incident.  Since January 15, I have been experiencing bloating. This bloating seems to be like my normal PMS bloating. As of January 24, still no sign of a period. Also, when I took plan B I was on my last day of my Z-pak for strep throat. The Pharmacist said it will not effect it. But, I'm still worried. 

 

Also, my last period ended December 31, 2012. My cycle usually runs 29-33 days.

 

I just wanted some thoughts and clarification. Anyone had a similar experience?
