Am I pregnant?

I had protected sex on may 2nd. We used a condom but I’m pretty sure it broke because when I stood up I felt fluid leaking out of me and when I checked in the bathroom it was a white substance. I took a plan b the next night assuming that everything would be okay. My cycle normally comes between the 13-18th of every month. I’m worried that I may be pregnant because I’ve been experiencing period cramping without actual bleeding for the past week and a half. However, this is the only symptom I’m having other than sick feeling here and there, which could very well be allergies too. I’ve had sex before this time but I was almost positive the condom never broke. Please help.
