Aww, totally understandable ang pag-worry mo, pero yan talaga ay common sa second trimester, ang breast tenderness comes and goes kaya di dapat mag-panic ka! A few of us moms noticed na parang nagbabago ang intensity ng symptoms as pregnancy progresses, so it's actually a good sign na kayo are adjusting well sa hormones. Ang white milky discharge mo is also normal sa pregnancy, so that part is actually reassuring. I'd still mention it to your OB on Monday just para ma-ease ang mind mo completely (doctors love when parents are proactive!), pero I'm pretty sure makikita mo na everything is fine. Breathe, mama, you're doing great and your body knows what it's doing!
