it's normal for your stomach to be soft in early pregnancy. it'll get hard again.
cramping is very normal and even some spotting but if you start to bleed heavy ever then I'd call your DR .....but I'm 18 weeks with twins and in the mornings my tummy isn't as hard as in the afternoons
Cramping is normal in early pregnancy, I wouldnt worry unless it gets really bad and you start to bleed. The bad taste in your month in normal too. With your belly, you may notice this all the time. Sometime if you have gas your tummy will get harder and or when the baby gets biger one side might be harder thats because the baby is on that side and then moves.....All very normal.
