Cd 50

All these looks negative to me but I’m 4 days late and CD 40 and 18 days past ovulation which I am not sure if glow is as accurate on that part. Am I safe? Can I say I am not pregnant? All if these are different days. Most current is the last picture. I have heard if you have testosterone in your system that you will have a hard time showing a positive.... my symptoms are sore boobs, cramps slight, and creamy discharge...are these just signs that my period is coming?? I’m totally freaking out and could use all the information y’all can give to know that I am safe this month. Longest cycle I have ever had is 45 days. Thanks girls
