So I'm ridiculously worried I'm pregnant. I missed a period right before I had sex so I don't know when my fertile window was. I did have my period less than a week after I had sex but I know that can still happen. I'm not sure if my partner used the condoms correctly every time. I've been doing a lot of traveling and haven't been an angel with my birth control. I've had a few random mornings of throwing up. My next period isn't till the 23rd. Thoughts??? I'm freaking out!
