So I went to a specialist yesterday for my baby, cause baby's dad has a heart problem...... after almost an hour in ultrasound, the doctor came in... I have to go back in three weeks, my cervix is short(was 2.87 now is 2.3) is it bad this is happening this early?? Plus my placenta's riding the top of my cervix, and they couldn't see baby's heart well enough...... should I worry? Will I be put on bed rest? Will I be able to make it to full term? Please help!
