I had a preterm labour at 21 weeks and lost my baby. i had severe contractions and my water broke? will it happen again in my next preg. no infection

Seek Napro : I'm so sorry!! this can be caused by infection, low progesterone levels, shortened cervix and unknown causes... So it is uncertain if it will definitely happen again... You will be considered high risk next time, they should check the length of your cervix, check for infections like bv, yeast, ... And if you know a Napro technology trained doc they can check progesterone and give back if needed
