looking for advice because I'm freaking out

Kayyyy
I have been in birth control for s year and always still had heavy periods because that's just how my body works but my leriod last month was light and only two days and I have never had a two day period and then this period was only for a few hours yesterday and now it's gone today . Should I be concerned about pregnancy I'm kinda freaking out . I plan to get a test after work but just had to ask because I'm a little nervous and just needed some advice or assurance
