I am now just about 25 weeks pregnant and for the last couple of days or so have noticed what I originally thought were Braxtn Hicks - painless stomach hardening. However, although it is still painless, it is just not going away within the usual couple of minutes and seems to last for 15-20 minutes or more at times. I feel well and happy, normal bp and can hear nice steady fetal heart beat - but am now getting anxious as these periods seem to be getting more noticeable and possibly longer (haven?t timed them as only just getting concerned). I tried phoning my mw a couple of times this morning but it is just ringing with no answer machine on. Anyone ever experienced this or similar or know whether I should be concerned, i would really like to ehar from you. Thanks
