So my boyfriend and I had sex on April 10th, we used a condom and made sure everything was good throughout it. My period was supposed to get here last Wednesday (April 29) but it hasn't gotten here yet. I know I'm not pregnant because we are very smart about things. Also, I've been working out almost daily so I'm thinking that postponing it...any words of advice or cheering up? I'm very anxious and don't know what to think or do at this point
