So my boyfriend and I had unprotected sex the day afte I was done with my period, and the next day we got the plan b pill. Took it at about 20 hours after we had sex. I had spotting 9 days after taking the pill that lasted for a couple of days. And now I'm up to the point where I'm about to start my period in a couple of days (but the thing is, my body is irregular so I never know when my period will actually start...) and I noticed some brown spotting that only lasted a couple of days. I don't know what's going on now with my body, am I pregnant or is it just the pill messing with me and this is something normal before a period? I've never experienced brown spotting before.
