I don't know what to think

Okay, so I've stressed myself out about a million times with the thought am I pregnant or not. I normally take my birthcontrol pill every day on time, but this month when I was sopposed to start my new pack somethingn came up and I couldn't pick up my proscription on time. I told my SO that I wasn't going to be on the pill this month and that we need to be careful. We don't use condoms (I know it's not smart) but we do use the  withdrawal method. I know that the withdrawal method is not safe to use but over the past year and a half it has worked for us. A few days had pasted since I told my boyfriend about not being on the pill, and after sex he asked if I had been taking my birthcontrol, I was so upset at this question because I had told him we needed to be careful this month bc I am not on the pill. He has this habit of not completly hearing things I tell him,  so we rushed out and bought the plan b pill it was about 4 or 5 days after my last period and we had had sex a lot durring that time when I had finally taken plan b. And now it's about 4 or 5 days after dpo and I'm having some werid things, it's still to early to test but I could really use feed back. My symtoms are that I'm super hungry and crave things I've always hated (blue cheese dressing) but my cravings are super super strong. I'm so bloated that I had to pin my work pants because they wouldn't fit and they fit me fine a weeks ago. I'm super moody and cry over nothing. I get really really tired at random points in the day (like I can't keep my head up or eyes open) but when I try to sleep at night I'm wide awake. I get random really sharp pains in my lower stomach like cramps but different. Idk what to do or think about all of this
