Virginities

So about a week or two ago, my boyfriend and I had sex. I'm not sure if I lost my virginty or anything but I did bleed a little. I've been having major anxiety about the possibility of being pregnant. My period shouldn't come on until next month and it's really hard waiting to see if it comes on because of all the anxiety.  I heard that stress makes your period take longer to come on.. What I'm wondering is, is this anxiety normal when you lose your virginity? The condom didn't pop but I have pretty shitty luck..
