chest pains? I'm very aware of things happening to my body, I have pretty bad anxiety and when having an anxiety attack my chest really starts to hurt right over my heart, after going to the hospital and doctor several times I know ways to calm myself and relax so my chest won't hurt anymore. Since before confirming my pregnancy I get random chest pains, it honestly feels like my heart, it hurts so bad I start to cry. Laying on my side or trying breathing exercises doesn't help, it feels like I'm being stabbed and like my heart is going to pump it's self out of my chest. I'm beyond irritated that my doctor keeps telling me it's just heart burn. Everyone says go with your gut, you know your body, about pretty much everything during pregnancy, well going with my gut IT'S NOT HEART BURN. It's not after I eat or before I eat or at any specific time, it's random and it hurts. I don't even know what to do. Is there a way I can have my ob do further testing or something?
