Hi. I’m 39 currently 19+3 pregnant with my first baby. I’m constantly worrying if she’s breathing or if I’ve miscarried. I’ve just gone out and bought a Doppler which isn’t picking up the heartbeat now I’m having a breakdown. I’m a little overweight so could this be the reason? What are the signs symptoms of miscarriage im so worried as I haven’t felt movements yet either. I’m petrified something bad is going to happen 😔
