Just kinda venting

So currently 8DPO today! Yesterday I got sick yesterday morning (I am a preschool teacher in the baby room so kinda get viruses) so just thought maybe it’s a Virus. Then I went home and fell right to sleep. Was soooo tired!After getting sick yesterday I ate a bowl of cereal. I still didn’t feel great all day though. Anyways then today this morning I felt sick but have not got sick. A few days ago I had mild cramping on my right lower abdomen. Not bad at all. Does anyone else have any symptoms at 8DPO or know if this sounds like i could be pregnant? I know it’s early though but I also can’t take a test right away because I have kidney disease and I guess the test can always come back positive with a very faint line. So I have to wait till my HCG levels are higher. Just getting anxious! So wanted to kind of just vent and maybe see when everyone else starts getting symptoms or could tell they were pregnant! Below is my app. I log it every time.
