Pulmonary Embolism?


So since this morning I’ve been having a sharp pain on the left side of my chest like above my boob, it doesn’t necessarily hurt to breath in but I feel the soreness and it hurts when I press down and I don’t have shortness of breath the pain is just there. At first I thought it could be a clogged milk duct, but I really have no idea. It also hurts when I stretch my arm back. I’m 6 days pp and an FTM so I don’t really know what a pulmonary embolism would feel like either. It’s Saturday so my OB’s office is closed 😕. Can anyone help me out on what I should do? It hurts right in the circled area maybe even a little bit lower.
