Sis, please go see your OB agad, 8 weeks is super important, at ang consistent na sakit at weird sensations need to be checked out right away, hindi lang online advice. Once you've seen the doctor and they've cleared you, honestly maraming mommy friends ko na nakaramdam ng ganyan during early pregnancy, ang hormones at changes sa body natin talaga wild, pero kailangan sure lang na lahat okay sa baby at sa'yo. Take care of yourself, and don't hesitate to go to the ER kung parang severe na!
