Could I be pregnant ?

[Worriedteenagerpleasehelpme]

Okay I had sex the 7th of June. I was on top of my boyfriend, when I came off of him I think I could have took off the condom by accident. He didn't climax , that Saturday to be on the safe side I took my way pill an emergency contraception pill. The following week I had sex , but it was with a condom at all times. I was active almost all week, I was fertile that week. But I didn't have sex on my ovulation day, on the 19th I had like spotting I guess you can say ? I'm not sure it was very light and wouldn't fill up a panty liner, I had that up to the 22nd. Now I'm beginning to have like white creamy discharge, but I've had this before. Just not as much , I've had some back pain, and this discharge , and last week I had the spotting. I'm not sure if it's the pill , because it has its side effects. Please help ! My period should come the second of July. But I'm freaking out ! Please someone help.
