I'm 24 and on birthcontrol pills, never take a pill more than 2 hours off schedule. My priods are supposed to come every four Tuesdays, but the last two have come 5 days early. The last one came Friday nov 2 (it lasted 9 days, they usually last 7). Additionally, I've been getting brown watery discharge for the past 4 days. I've never had irregular periods or strange discharge before, EVER.
I was last sexually active until exactly a moth ago, always used condoms or pulled out because I'm paranoid. Still I'm worried, could I be pregnant? Could it be something serious?
