fears of miscarriage

i’m 24+6 and constantly having fears of miscarrying or premature birth. a few days ago i had some discharge that looked a lot like my mucus plug so i showed the nurse a photo and she said it was discharge from my cervical exam i had done the day before. but there was a lot of discharge and i also in the hospital for bleeding the day before. they checked the heart beat and said everything was fine and i had an ultrasound but it was only to look at my cervix. i just really really hope my baby girl is going to be okay and makes it full term. does anyone else stress themselves out to the max with these things..

edit: and today i had a small bit of a grey discharge!! it might be from the exam but i just don’t know anymore. i don’t have an obgyn to call either so i need to go to the hospital every time this stuff happens
