I got my period 3 times in one month?

Alyson
I don't know if I had extra heavy spotting, or if I need to go see a doctor, all I know is that it's concerning. I got my period early in the month and, because of my birth control, it only lasts for 3-5 days unlike my usual 6-8. Then I got my period AGAIN! I had all the symptoms of a usual period but it started on the 14th and lasted still the 19th. Maybe it's just heavy spotting but now it's the 26th and I woke up to me bleeding through my pj's with cramps! I have no idea what's going on, please help.
