so me and my boyfriend had sex the 7th of July and he pulled out and we used a condom. then the 30th of July we also had sex, again condom & pulled out. I was supposed to get my period that coming Saturday the first, it's now the sixth and it still hasn't come. I'm extremely scared and just need some words of advice. :( also the day I was supposed to get my period I got like pre period symptoms :(
