Curious... Cuz maybe I might be please respond

So I'm 21 yrs and kinda curious about me being pregnant well it started I was late for my period for 2 days so I got the test and did it and it showed that their was a faint line, so I tried again and it was the same so I waited another two days and it it again and still the same and I was kinda nervous and now I'm late 6 days but then I got my period... But it's kinda different from my other periods and I was wondering can you ha e your period and be pregnant??? Please need to know I'm not by myself
