Mama, kaya mo yan, marami talaga sa amin ang dumaan dito, at honestly ang anxiety during pregnancy is so real and valid. Ang good news is, ang palpitations at panic attacks mo ay manageable with the breathing exercises you're already doing (deep breathing talaga works, right?), plus your hubby is right na rest and relaxation help a lot, pero for peace of mind, definitely bring this up with your OB at your next visit kasi they can monitor you properly and maybe give you strategies na safe for pregnancy at labor. Maraming moms with anxiety ang nag-deliver normally, pero ang bawat pregnancy is different, kaya better na i-discuss mo directly with your doctor kung ano ang best approach para sa inyo, they might even prepare you mentally para sa labor so you feel more in control. Kaya mo to, mama!
