Question

Has anybody had an aching pain under your boobs starting from the right and going to your left side and going towards your upper back? The first time I’ve experienced this was saturday night before going to bed it lasted about 2hrs so not being able to take the pain I went to the ER and they just said it was heartburn but then again about an hour ago it happened when i was asleep and i woke up not being able to breathe and the pain stayed for about 30 minutes when i decided to see if a bath would calm the pain down it did. Today I’m exactly 16 weeks and I’m only scared about this pain because I wasn’t able to breathe has this happened to anyone where the Dr said it was a heartburn but it was honestly something else?
