Ladies I need help.

Im 28+3

From my previous post about the increase in discharge etc etc...could this be related especially to symptoms of early labour.

..Last night I had heartburn but it was terrible heartburn it actually felt like fire along with insane nausea...it made me wake up at 2:30pm and run to the bathroom and because I hardly ever throw up...It just made me cough and the throwing up feeling disappeared...but nausea was not done yet!eventually I fell asleep and I woke up and my stomach feels extremely weird....and nausea is back more than ever(never had morning sickness nor have I thrown up in the last like 3years)My tummy is not runny at all ....ive actually googled this and it said it can be early labour symptoms?Is this true?Any help or advice appreciated (understandably "go to the dr" is going to pop up a lot but I dont want to bother my hubby if its just not much to rush to the er for)....I havent eaten since about yesterday 7pm? And I just went for a number 2 about 15min ago (tmi sorry ) ?

Also sharp pain in right shoulder that cms and goes
