Trying to Conceive for the First Time

My husband and I are trying to conceive, this would be our first time being parents. It's been about two weeks since my ovulation and I'm not sure if I'm misinterpreting my stomach pain of today. Funny thing is that just last night I felt super dizzy and nauseous. I'd like for someone to give me feedback. I don't know if I should take a pregnancy test or not because I am supposed to get my period by Friday. I would really like some advice & feedback. Thank You❤
