Do you think i'm prego? **please help!**?

So, I had my period May 23rd. It lasted 5 days. I had unprotected on June 1st around 12:45PM. Without getting too graphic let's just say he didn't "finish off" since we didn't have a condom, the whole ordeal lasted less than 2 minutes (i know right?), I took plan b one step the next day at about 11:00 AM because I really didn't want to get pregnant since I'm only 17.(i know i know, i'm an idiot. unprotected , any kind of is stupid and i know i'm not ready now, hence why i took plan b) And here's the deal, I've been having cramps ever since, granted they're light cramps compared to what I get during my actual period. It's been a week and a day and I know abdominal pain and cramps are side effects of the pill but it said that they wear off after about 3 days. I also had discharge earlier this week, it was pretty clear. Has anyone gone through this kind of thing before? I'm just incredibly paranoid and I am FREAKING OUT. So recap, Just finished my period, had sex about 4-5 days later, he didn't *** and it only lasted about a minute or two, and i took plan b roughly 22-23 hours later. What do you think the chances are of my being prego?
