Hello po 17 weeks pregnant po ako normal poba ang pagtigas at pagsakit inaabot po ng 3 to 5 minute?

contraction may happen which is called braxton hicks. pero ito ay hindi persistent. kapag nagpalit ng pwesto or position, mawawala. contraction lasts about ilang seconds lang, not more than 1 minute. if persistent, inform OB. its not normal since 17weeks pa lang.
