helpppp

I just went in for a pelvic exam yesterday? And took a blood test. that came back to all my numbers at 0 and so it says I'm not pregnant anymore. My obgyn had called me and told me that today, but then earlier tonight my family doctor(one who isn't a baby doctor, just a family doctor) said she wanted to talk to me about my test results and wanted to get a couple more tests ordered.. I have no idea what those could be? So now I'm getting worried.. but, is it normal to have red discharge after a pelvic exam? I also was having this stomach pain that came and went just for a little bit.. I don't know if that's cuz I just started working again today? Or what.. I've been off for 2 weeks since my miscarriage. I had a pelvic exam done yesterday and now today I got some red discharge? We've been trying again because I'm not having miscarriage bleeding anymore, so just curious what this could be? Obgyn did tell me to wait a few cycles so my body can get back to normal, but we obviously haven't....
