Congrats sa pregnancy, mama! Honestly, chest tightness in early pregnancy is pretty common kasi maraming hormonal at physical changes nangyayari sa katawan natin, pero since it comes and goes, it's still best to mention this sa OB mo sa next check-up para ma-assess properly, hindi ito something to worry about ngayon, pero good to get it checked talaga. A few of my mum friends experienced similar sensations during their first trimester, kaya hindi ka nag-iisa, pero palaging better to be safe, di ba? Congrats ulit, at excited na kami for you!
