Having a HGC blood test tomorrow

Cat

I’m so nervous, my period is 17 days late and I’ve taken some pregnancy test and only 2 of them had faint lines and the rest were straight negative. I called my doctor and she told me to come and do labs and she has had a women that was 15 days late and they did a ultrasound and she was pregnant. And the test were all negative for her as well. My doctor said my symptoms sound like the other women... please need some baby dust!! Me and my partner have been trying for 5 months after I had my iud taken out in early September
