i agree to go get checked out... if something is causing you discomfort then its best to find out what it is :) i had simular pains right in that area... its was a pretty intense stabbing pain and it normally occured in the evening... it turned out to be an ulcer... but your Dr would know more ;)
Heart palpitations are common during pregnancy... with the additional hormones, increased blood flow and stress that goes along with it... but still you should inform your Dr that youve been experiencing them, as with any other complaints you may have :)
But anyway Congrats on your pregnancy!!!
Well i was in tha same siuation before n i had a upper respritatory infection
Anytime You have any sort of chest pain it is best getting it checked by a medical proffesional especially with little one to look after as well as Your health.
