Congratulations on your pregnancy! At 5 weeks, your baby is still so tiny and development is happening pero walang worries pa, kung normal ang pregnancy mo so far, everything should be progressing well, pero really best talaga na i-confirm ito with your OB para ma-check nila personally kung lahat ok. A few of us mums got so anxious din in early pregnancy, pero once nakita namin sa ultrasound yung baby mo kahit konti lang siya, sobrang peace of mind talaga!
