Mama, I know it's scary lalo na first baby at you're at 6 weeks, pero please contact your OB or go to the clinic today para ma-check, okay? Any spotting in early pregnancy needs a proper ultrasound and examination, hindi lang online advice. A few of my mum friends had light spotting rin, pero each situation is different, so kailangan talaga ng doctor's eyes on you. The abdominal discomfort with certain positions is something your OB needs to know about din. Don't worry too much, but get checked soon, better safe than sorry, lalo na ngayon. Take care, mama!
