am I pregnant?

Victoria
Okay, everyone. I'm two months late on my period and this started after unprotected sex. I've been bloated, a little crampy, moody, the bottom of my stomach feels harder, discharge, so tired, nausea around 4 am sometimes, sore breasts, etc. I had two positive pregnancy tests but after a few minutes the first line faded. I had a blood test and they said there was less than 1 hcg. I've seen plenty of woman that they didn't detect the hcg until like 4 months but idk I'm worried. Could I still be pregnant? does it sound like I am?
