I went into preterm labor at 28w with first preg. this preg (2nd preg) 1st cervix length check was 4cm, 2nd was 3cm, 3rd was 2.52cm. dr suggested follow up in 2 weeks after i pushed for it. not on progesterone. should i make a sooner app?

If pre-term labor was a result of cervical incompetence, the progression at this point in your second pregnancy (information about the weeks current pregnancy has reached is missing), suggests a possible repeat start of early labor. Cervical circlage may be necessary at this point, so get a second opinion from a maternal-fetal OBGYN physician as soon as possible.
