hcg level 86..

So I went to my first doctors appt yday and took a blood test. I got my bfp last thursday and AF was supposed to be last friday according to the app. I have irregular periods so I cant say the app is accurate. I got a call back from my doctors office today and My HCG level is at 86. My doc said this is very low and I'm very early in my pregnancy and that it could be an abnormal pregnancy. This made me very sad to think that I'm probably not pregnant. Im going to go back to take another blood test in a week to see if the HCG levels are increasing. Anyone else experience something similar with irregular periods? I'm also experiencing cramps and sore boobs atm and had some food aversions last week and felt a bit nauseous. I'm also supposed to be at 6 weeks and 2 days today. please pray for me ..I'm hoping that I am pregnant and it's not a chemical or anything ...

The top HCG test is yday and the bottom is from today. what do you guys think? Should I be worried? I'm hoping this is a sign that my HCG levels are increasing..
