Ttc but what the hell is going on

I forgot my test cause I got busy went back an hour later and had this but it makes no sense cause AF is regular and on time but this month I was 7 days late and then started and went only 4 days and stopped I don't understand it what the hell is going on and I have had no stress no chance in activity but for the last week I have been queasy and feeling like I have a fever even though I don't along with headaches pretty much every day
