@itsmemikii,
Go back and reread the post you replied to. Anything is possible, but it's highly unlikely that you're pregnant. I don't think you're pregnant but given how worried you are about it I think you're going to be late for your next period. Depending on the test you take you can take a urine test in another 10 days, or so. Take it unless you start your period beforehand. Buy a double test so that when the first one is negative you can take the other one three days later. It will most likely also be negative. Believe the results. The tests work well. Once you've seen two negative pregnancy results and allow yourself to believe that you aren't pregnant you'll start your period.
It's ok, osso, I went through it myself when I was younger and both daughters went through it to.
