Not sure where I belong

​I don't know if I'm still pregnant and I don't know if I miscarried. I'm fighting the diagnosis. I know my period was April 29th, I didn't ovulate till may 23rd, my mom told me before birth control when I was 13 I had long irregular cycles that were painful and caused me to have anemia and get really sick. Had an ultrasound today and they said I was measuring 7 weeks and there wasn't a heartbeat, my dr went off my last period and says I should be 10 weeks. I'm going to call my dr on Monday and try and get in to see her soon and have more blood tests done because I had blood tests done on Thursday so if I get more done that will tell if I'm miscarrying right cuz the hcg hormone will decrease right? I also want to ask to wait and have another ultrasound to be sure in 2 weeks. I want to give this baby a chance cuz I don't know where I am now in all this. I feel lost and confused. And then I get home and find out one of the kids I daycare full time wont be coming with me anymore because they're going to Kenya for a while, and so that's my income. I run a daycare. And now I'm pregnant but not pregnant and I just need something good to happen today and everything seems to have gone wrong.
