Mama, please contact your OB or go to a clinic to get that checked out, 7 weeks pa lang kayo, important na sure na okay ang pregnancy. Hindi kami dapat mag-assume, lalo na kung may pain kahit mabilis lang mawala. One of my mum friends had something similar and turned out it was just ligament stretching, pero kailangan talaga ng doctor to confirm, better safe than sorry, especially ngayon pa lang kayo! Let me know how it goes, okay?
