HELP!! First time mom!!!

I’m 26 weeks pregnant and three days today and this morning at 4:00 a.m. I went to the bathroom to pee and when I wiped I noticed I spotted. This is a first throughout my whole pregnancy so far and it’s got me so shaken up. I don’t know what could be going wrong. I have an appointment this morning at 8:30 already and I’m scared it’s going to be bad news.....
