Fussy Baby, need advice

Lisa

So for the past two days my baby hasn't pooped. Normally she would have about 4-8 poopy diapers a day. all of a sudden she just stopped pooping, started having a ton of gas and pushing really hard. We would slowly work out the gas, we tried simethicone, shes on the probiotic from Gerber but it doesn't seem to be getting any better. I called the doctor yesterday and essentially they don't wanna see me unless there is blood in her stool. However there is no stool and now this kid is pushing so hard shes spitting up her milk immediately. shes clearly in a lot of pain and nothing is really soothing her anymore. she chokes whenever she drinks off bottle and boob. I'm at such a loss.
