Do you think I’m pregnant 😩

Okay no judging please, I already have one child and am not really looking to have another one for a couple years I recently came off my insurance and have no money to get birth control or depo, etc. I took plan b twice last month (I know it’s bad) i was supposed to get my period about 6days agoI’ve been having really bad lower back pain especially when I lay down and I’ve been cramping but there’s no signs of my period. I know I have a child but honestly it was so long ago I’ve forgotten my early symptoms. Are these pregnancy symptoms ? I’m taking a test tonight but I wanted to see what you guys think. (I will update)
