Should I be concerned???

I’m 6 weeks pregnant, almost 7, and last night while cutting my husbands hair I randomly got sharp pains in the left side of my chest, arm, shoulder blade, back, neck and head. Breathing seemed almost impossible. It was difficult to catch my breath and painful.

For the last few weeks, maybe even 2-3 months, I’ve had to hold my chest if I have to sneeze or cough or else the pain is terrible.

My husband and mom say I should go to the ER but idk...
