Uy mama, kaya naman yan! Sa 7 months, chest x-ray is generally safe, importante lang talaga na sabihin mo sa radiologist na buntis ka para ma-shield nila properly ang baby. Maraming moms na dumaan sa ganyan, kasama ako actually with my first, at lahat fine kami. Three weeks of cough plus antibiotics na hindi umeffect is concerning talaga, kaya better to get that imaging done para makita ng doctor kung ano talaga ang nangyayari sa lungs mo.
The lead apron they use protects baby, at ang radiation exposure from a single chest x-ray is very minimal, mas risky actually kung hindi mo aayusin ang infection at asthma mo while pregnant. Pero syempre, when you go for the x-ray, confirm ulit with your OB at radiologist na lahat ng precautions are in place, at ask kung may follow-up treatment na pregnancy-safe for your asthma. Better safe, better prepared.
Wishing you better soon, mama!
