Lack of symptoms

Has anyone had a previous MMC (or two) where they lacked symptoms during that whole pregnancy and then lacked symptoms with a subsequent pregnancy and had a healthy baby? I had two MMCs last year with minimal symptoms. I'm now almost 6 weeks pregnant with minimal symptoms again and am scared to death this baby will leave me by 12 weeks too. My ultrasound isn't til the 2nd so just looking for reassurance. Thank you.
