help please!

Hello, I really need advice. So my last period was the 15th of April and my cycle is 26-28 days, and today is day 29 and no AF :( I haven't had unprotected sex ever, I'm still a virgin. But, I have engaged in mutual masturbation with my boyfriend. One time he was over me and I think he came, but it was in his pants and I didn't feel anything and we are very careful, so if he did we would've known I believe. Also, a week before my period I lost a loved one and vomited and couldn't eat for a day or two. I was at the end of my ovulation when this occurred . What are the chances I am pregnant? I have my signs for AF; sore boobs that get better as time goes on (because af is soon and progesterone is decreasing), i had bad breakouts about a week ago, and I'm a bit bloated along with my cm has been creamy/cloudy/drying up which happens to me before af. So, could I be pregnant? Or is it stress?
