Threatened misscarrage

Amy • Brody was born 7/29/16 after having a ectopic July of 2015
Woke up lastnight feeling like I had to pee when I got up it felt like I peed myself. When I went to the bathroom it was blood so much that I woke my husband up to go to the ER. They did a ultrasound found baby heart rate was 164 said I was 8 weeks 2 days hcg was 80,000. They told me I had fluid on one side of my uterus but couldn't find a subcronic bleed. They ended up releasing me with a threatened misscarrage. Has anyone had this happen and end up having a healthy pregnancy? Trying not to panic on something I can't control.
