Over stressed?

I had sex with my boyfriend and he pulled out with plenty of time before he cummed. My period just came and I know it is only the first day but it is really light and I’m not sure if it is from all the stress I’ve been going through with college and there’s been a lot of drama in my family this last week that has got me very anxious and upset. I think my head is trying to create more problems and I know I do worry more on my period about dumb stuff so is this just me being stressed?
