He might have came inside me...

So me and my boyfriend just had sex and he thinks he came inside of me, there’s a line of cum on my blanket but he doesn’t know what exactly happened he didn’t tell me it happened either until he started freaking out thinking about pregnancy. This wasn’t supposed to happen as I’m on my period and we got so lost in the moment that we didn’t use a condom... can i be pregnant?
