2nd period this month ??!

Georgette
I just got done with my period on March 6... It was about a week long and now I just went to the bathroom and I'm bleeding again ! It's in my underwear and on the toilet paper when I wipe it's not light but not heavy. What's wrong with me ? I mean me and my bf have unprotected sex and he finishes in me but this can't be implantation bleeding right I mean I just had my period and in glow it didn't say I was ovulating. I'm really worried :(
