Emotions

Danielle • I am 34. I have 3 children I had miscarriage in 2015. I'm currently pregnant with our 4th child due October 21.
With my miscarriage baby I knew  something wasn't right from get go. I started spotting then to bleeding. I pushed for ultrasound and I was unfortunately right. 
This pregnancy already feels different. I feel like everything will go good. Doesn't mean I'm not checking for spotting every time I pee. I'm still anxious. I'm only 4 weeks 3 days so I'm at critical part where placenta is attaching. The dr already checked hcg and progesterone at 3 weeks 6 days. Both were good he's not concerned. Due October 21
Anyone else understand what I'm feeling about just knowing?
