Congratulations sa baby number two! Honestly, every pregnancy is different talaga, nung first ko naman mas maaga ako nag-crave ng weird things, pero ngayon mas prone ako sa heartburn kaya hindi ka nag-iisa dito. Stomach aches can be normal sa early pregnancy dahil sa hormonal changes and ligament stretching, but since it's bothering you and it's different from your first time, mas okay na i-check mo with your OB just to be sure, especially pag persistent or may spotting, better safe than sorry, di ba? Alam mo naman rin na bawat pregnancy and bawat mama ay different, so your doctor will know what's best for you and baby.
