Ay mama, with any changes sa cervix at 37 weeks, you really need to see your OB right away or go to the hospital para ma-monitor properly, better safe than sorry, lalo na kung may doubt ang doctor sa consistency. Hindi kami dapat mag-guess dito kasi bawat pregnancy is different, at kailangan mo ng proper medical check to know kung normal pre-labor signs lang yan or kung kailangan ng intervention. One of my mum friends had similar situation at inmonitor lang siya closely, kaya go na sa doctor para ma-rule out any concerns. Fingers crossed for you, mama!
