To be or not to be

Although we're not actively ttc yet, my husband and I have been having unprotected sex and we've talked about wanting to have a baby very soon. the last week I've been really bloated but not having much gas, eating alot more, knees aching, things like that. It's 3 days before I'm supposed to start my next period but hoping it won't come :) don't know if I should wait a few days or take a test now?
