What do you girls think?

Hi ladies! I need some advice! So lately I have been getting different kinds of discharge from white lotionish discharge in small amounts to fair amounts of sticky gooey mucus. Yesterday it felt like I was about to start but the cramps were a lot stronger than usual. I just figured it was going to be a horrible period😩. I was real wet down there all day yesterday. And that isn't quite normal for me. I was getting small pains in my back right under my ribs. I didn't know what to think. Every time I moved it hurt. And the cramping was worse when I sat down. I was suppose to start today so I did the qtip test but there was nothing on the qtip. I am hoping I am pregnant finally but I do not want to give my hopes up. I have a test but I am going to wait a couple of days before testing. I just want to know if anyone had these problems and found out they were pregnant. Also the cramping is like a stabbing pain almost, as if I have a knife inside me😭

Go ahead and tell me how you found out you were pregnant, when did you feel like you were kind of off?
