Aw, first time mom jitters, I totally get it! Yung parang flutter or pitter-patter na feeling sa puso, lalo na kapag malakas ang tibok, pwedeng normal lang especially ngayon at 14 weeks kasi ang katawan mo ay dumadami ng blood volume para sa baby, pero para sure ka talaga at makatulog ka ng mahimbing, best to check with your OB kasi siya lang ang makakapagsiguro if it's just Braxton Hicks vibes or something else. A few of us mums experienced weird heart sensations during pregnancy and turned out fine, pero peace of mind talaga ang importante, so don't hesitate to text or call your doctor about it!
