Weird period? Could I be pregnant?

Taylor

So, me and my boyfriend have been trying for about 2 months now. I thought for sure I was pregnant this time I felt really different and my boobs hurt a lot more then usual and I couldn’t stop eating. I also just randomly stopped craving soda I just want Gatorade or juice which is not normal for me. The two days before my predicted period I had horrible lower back pain that radiated to my hips and then down the back of my legs. I started 3 days after I was suppose to and ended up getting sent home from work because It was so bad I couldn’t walk. I went home slept most of the day took medicine and then was able to move about. I had to wear a tampon the first day. Well, today I haven’t really bleed at all it’s more of a clear stretchy liquid almost like snot discharge. It’s kinda tinted pink every now and again brown. But no bleeding. Does this mean something? Should I test again? I tested the day before my predicted period and it was negative. Stuck.
