Pink discharge for 4th day 8+2

Analise
This is my first pregnancy after miscarrying over a year ago. I started with pinkish discharge at 8w then, took 2 weeks before the cramping and bleeding to start, and then 4 days of straight hell. I knew straight away then what was going on, but I don't have that same sense now. I'm still terrified and I can't get in to see a doctor until I take this stupid new parents class the military makes us take. I've been pregnant 3 times prior, given birth twice, think I've got it! Anyone else have this or had it and came out fine the other side? I'm trying not to dwell on it, but I'm scared it's going to happen again.
