need advice

So, I'm a little worried... my last period was the 20th of march and my boyfriend and I had sex the 21st the condom broke and my period is due in 6 days, but I've been cramping pretty bad since the 22nd and it hasn't stopped I'll have random moments of like binge eati g hunger where I can't get full and my boobs have been killing (almost like the growing pain you get sometimes) and my mom was feeling of mylower abdomen and it hurt really bad, I've also had diarrhea for 20 days straight... sooo I guess my question is has anyone ever felt like this because I'm feeling insane.. I'm also a diabetic and I'm 20 years old, no birth control.. I don't think this is any kind of pregnancy symptoms but I need advice  😔
