anxious? intuition?

me and my bf we're having sex literally before/during/ and after ovulation. unprotected the whole time. i feel like i know exactly when i conceived but i also want to tell myself i'm being paranoid. i have 6 days until my period is supposed to come. i wish i could take a test now but i want to wait to see it it'll come or not..i'm just nauseous sometimes with terrible mood swings and i eat anything i can. and im peeing all the time. these can be related to my period but the only thing i remember being a symptom before my period is being bitchy. any thoughts? advice?
