Bad stomach pain

So like 2 minutes ago I began getting bad stomach pains i had to go lay down because it hurts, it also feels like i have cramps in my side.

I had unprotected sex a week ago and also 5 days ago.

My next period is in 12 days💀 I’m scared to tell my boyfriend that i have stomach pains because he’ll just get annoyed or worried and tell me to take a test then I’ll say its too early then he’ll just get angry and shout at me..

So idk, but the app says i just finished my fertile window so🤷🏽‍♀️ and on sunday i was having abdominal pains in my side and stuff and im having lots of discharge
