Hi mama! Please go see your OB as soon as you can, pag may pain sa pregnancy, lalo na specific area like yan, importante talaga i-check para peace of mind mo at sa baby. It could be normal stretching or ligament stuff, pero alam mo naman, better safe than sorry sa 8 weeks pa lang. One of my mum friends had something similar at the doctor said it was nothing, pero she's so glad she went kasi nag-worry siya ng maaga. Hugs, and please don't delay the checkup!
