Not feeling pregnant

Ashli

Ok so I'm 14 weeks and 3 days. All of my pregnancy symtoms have dissapeared. I had a 12 week ultrasound. Everything looked good and baby had a hb of 160. I just don't feel pregnant anymore. I'm kind of worried bc i had a miscarriage last December and my son died at 8 months 4 years ago due to complications from being premature. Am I being to dramatic or is there something to be worried about?
