My girlfriend's period is late, but is usually very irregular.  We use protection, but there was a time where we were going to have sex a second time after and I put a condom on wrong before putting it on the right way.  (This was over a month ago.)  She has been cramping and bloated expecting her period but has began spotting instead.  She is going to get a test on Saturday but we are both very anxious about the possibility of pregnancy.  

Please answer quickly I'm very nervous.
