Need advice :)

Hi! I had sex during my fertile week. He didn’t cum and the condom didn’t break. We blew it up like a balloon and filled it with water. My period was supposed to come yesterday, it still hasn’t. My boobs usually start hurting before a period - but I have no breast pain? I’m thinking maybe I ovulated late or something? But I don’t know. When should i test or should I test at all? Do you think I’m okay and not pregnant? Thank you in advance!❤️
