Helppppp

Sooo last month on June 7 I got my period that last four days. On June 26th I got my period again with lesser symptoms but lasted six days. My period was once irregular when I first got it at 11 but when I was 16 I was out in birth control and though I'm not on anything now, my period is regular and comes usually the day two days after the app tells me. But me and my boyfriend had sex in the very beginning of the month with a condom and he came and took it off and then we had sex again without anything right after. And have used the pull out method since then(a month ago). Could I be pregnant? Or my hormones just off? I have been craving sunflower seeds and combo's pretzels and literally nauseous everyday. Also, had very clear runny-like discharge and a lot of it about two days ago but my calendar calls for me being fertile. But I've had diarrhea. Idk I'm just very nervous
