I need help ...

Right so I don’t know if I’m just being paranoid but I got the bar in last Friday which I think it was my 6th day of my menstural cycle, I had sex on the Sunday and the condom got stuck and when I took it out it was in a ball so I took the morning after pill within 24 hours. Then I had sex again this Saturday and the condom broke but he didn’t cum inside me. Right now I’m having symptoms as if I’m getting my period but I’m not due for 12 days so I’m really worried is there a chance I could be pregnant? Or am I over thinking this way too much?
