3 days late

I'm three days late. Normally I get warning cramps a couple days before I start bleeding, but I haven't at all. My husband and I had sex on Valentine's Day for the first time without using a condom. It was also at the end of my ovulation stage. I know I just need to take a test and see, but do you think I could be pregnant? We're out of town visiting relatives and we're waiting to take a test when we get back home, but I'm freaking out!!! Haha any thoughts or experience on this? Is it too early to start hoping I'm pregnant??
