Pregnant?

Okay so my boyfriend and I had sex right as eve predicted my fertile window opened, we used condoms and he didn't cum while he was inside of me, we had sex twice both times using a different comdom. And he put water in it after wards to test it and there was no holes. And I'm new to sex so every time I do it I get SO paranoid that I'm pregnant. My periods due next week. I'm not showing any signs, am I crazy?
