My both daughters exceed EDD. It depends on individual body as braxton hicks are just signs that your body is ready. But definitely second baby will be faster for some (my baby too comfy 😅) For full term 37 weeks onwards. Anything earlier will be preterm, but dont worry, as long as you dont have any other signs of labour like mucus, tense contractions, waterbag leaking you will not deliver that early.
It doesn’t matter girl or boy, it’s really up to your own body and baby’s cue hahah…. However most second time mummies find that baby will come earlier compared to first pregnancy.
