so yesterday I felt fine for the first time since I was 5 weeks(I'm 9 weeks now). today I thought I was feeling ok till I got to work and my body got extremely hot and cooled down fast and it made me almost pass out/faint. the lady I work with said its a good sign to have sickness because it means your hormones are working right. I'm just scared because I use to pass out/faint about 5 years ago:/ has this happened to anyone else while pregnant? I'm really scared because j have miscarried before and I just don't want anything to happen to my blessing. I have a doctors appt tmrw but I'm really really scared now:'(
