... morning. On Saturday/Sunday midnight I realised that I hadn't taken Friday or Saturday's pill yet (something that never usually happened). I quickly took both and the next morning took Sunday's pill as usually. I was in week 2 of my cycle and have now entered week 3 (it's currently Monday). My partner and I had unprotected sex Friday and Saturday night. I'm nervous about my chances of being pregnant. I would like to know, what are my rough chances of being pregnant and should I take a Plan B/Morning After pill to be sure.

Note: I have started using condoms in case it is inactive for the next week.

Thanks
