Am I more than likely pregnant ?

Okay, so this may be dumb, but I’m freaking out lol

I usually get my period around the 28th of every month. When I was on the depo shot, I didn’t have a period. But when I switched to the pill, I had a period every month. Well, 3 months ago, I had two periods both months. The first ‘period’ I was early. Like it came around the 5th or 6th of both months. I had really no period symptoms, and they went away after about 4 days. Then On the 28th, I started and it was like a normal period for me. This was both months Incase I lost you lol. So now it’s June, and I have not had a single period for the month of May, and I’m freaking out. I’ve started working late, so I sometimes will forget to take a pill, but the next day I will take the one I missed and the pill for that day. (I know, y’all! Please don’t chastise me! I am very forgetful and irresponsible sometimes!) So me and my boyfriend (of almost a year) have been having sex whenever I get to see him, which is like two or three times a week. I have no idea when I would’ve gotten pregnant, and I’m not really showing any symptoms, but my period being this late is really freaking me out. It’s came early before, but I’ve never been over a day or two late. I may just be overreacting, so please no one be mean and laugh if I am. I am 18 and really really don’t need a child, so I’m kinda stressing and thinking the worst (even tho it would be a blessing, I’m not ready to have a child. So no one get offended by my last statement please.) So please, someone help!
