I went to the gym for the first time since i got pregnant we worked out arms legs stomach walking I'm very obese and I'm 20 weeks we went into the steam room for 10 minutes tops. I ate a lot of spicy food today and then greasy sausage for dinner anyway I can't feel the baby moving anymore he always moves when I lay on my stomach it's my first baby and I'm very scared that he died I can't go to the drs.
