Abnormal bleeding and freaking out

So I got my period the first of February. It lasted about seven days the usual. My bf and I had sex on February 9th. We used a condom and he didn’t cum. We also checked the condom to make sure it didn’t break or tear and it didn’t. While I was fertile and ovulating we had no sex. I got my period on March 3rd and it lasted the same seven days. My bf and I haven’t had any sex since Feb. 9th but today I had some bleeding. I did just get done with ovulating and like I said there hasn’t been any sex. I have been stressed out lately with being a college student and work, but I’ve never really bled from stress. It’s freaking me out could something be wrong? Is bleeding in between periods normal? I feel it’s too early to be my period. I’m really freaking out!!
