About 4 weeks ago I had protected sex a day before my period was due to start the condom kept slipping off into me so we stopped 5 minutes in he didn't finish I'm sure. I took a Plan B pill almost 3 days later and I started bleeding unexpectedly a week or so later. I then had protected sex after that sometime but he finished outside of me in the condom. I'm supossed to start my period in 2 days I have some pain in my hips I'm really dizzy and it's not from my period I'm almost certain. I have been really stressed about it lately. Any ideas on what could be going on. Is the plan b pushing my period schedule back or am I pregnant. I haven't taken a test because I'm just turned 18 and I'm super nervous for that step alone.
